The LTC7103-1 is a high efficiency, monolithic synchro-nous step-down DC/DC converter utilizing a constant frequency, average current mode control architecture. It operates from an input voltage range of 4.4V to 105V and provides an adjustable regulated output voltage from 1V to VIN while delivering up to 2.3A of output current.The LTC7103-1 features high frequency operation and a low minimum on-time that reduce inductor size and enable constant-frequency operation even at very high step-down ratios. In addition, the LTC7103-1 achieves the lowest possible dropout voltage with 100% maximum duty cycle operation. During light load operation, converter efficiency and output ripple can be optimized by selecting Burst Mode, pulse-skipping or forced continuous operation.The LTC7103-1 includes accurate, high speed average current programming and monitoring without the need for an external sense resistor. Additional features include a bypass LDO to maximize efficiency, fixed or adjustable output voltage and loop compensation, and a wide array of protection features to enhance reliability.Compared to the LTC7103, the LTC7103-1 is pin compatible, except that it also offers continuous inductor current mode.APPLICATIONSBattery Chargers and CC/CV SuppliesAutomotive and Military SystemsIndustrial, Avionics and Heavy EquipmentMedical Instruments and Telecommunication

LTC3372EUK#PBF Demo Board | 6V ≤ VIN ≤ 60V, VOUT_HV = 5V or 3.3V @ 10A; VOUT1 =1.2V @2A, VOUT2 =1.8V @2A, VOUT3 =2.5V @2A, VOUT4 =3.3V @2A
Analog Devices Inc.
Demonstration circuit 2419A features the LTC3372 in a
multi-output step-down converter. The controller portion
of the LTC3372 drives a high output voltage (HV) buck
converter which has an input voltage range of 6V to 60V.
Its output voltage (VOUT_HV) is nominally 5V but can be
configured for either 5V or 3.3V with the VOUTPRG pin.
VOUT_HV supplies power to the configurable buck regulator.
This regulator provides four low voltage (LV) outputs
labelled VOUT1-4. These outputs are 1.2V/2A, 1.8V/2A,
2.5V/2A and 3.3V/2A respectively. When VOUT_HV is configured
for 5V, it can supply 6A to the external loads with
full load on VOUT1-4. With no load on VOUT1-4, VOUT_HV
can supply 10A to the external loads.
The LV buck regulator consists of eight power stages that
can be arranged in up to four channels. The LV regulator
on the DC2419A is setup for four channels of two power
stages each. With modifications, the LV buck regulator
can be setup for eight different configurations.
If VOUT_HV is programmed for 3.3V, then VOUT4 which
provides 3.3V/2A will be in dropout. This rail will require
an external input voltage to stay in regulation.
The LV rails operate at 2MHz and the HV converter operates
at one-sixth this frequency or 333kHz. The high frequency
of the LV rails allows the use of 4mm × 4mm
inductors. The power stage for the HV converter consists
of 60V avalanche rated MOSFETs and a 2.2μH 10mm ×
10mm inductor. A 4mΩ discrete sense resistor is used
to sense current.
The low IQ current of the LTC3372 provides high efficiency
at light loads. When the VOUT_HV is supplying the nominal
5V, its Burst Mode® efficiency with 1mA load is 90.3% for
a 12V input. When the HV converter is off,
it only draws 27μA from a 12V input.
The LTC3372 data sheet provides a complete description
of the IC operation and application information. The data
sheet must be read in conjunction with the quick start
guide.

The ADuCM322 is a fully integrated, single package device that incorporates high performance analog peripherals together with digital peripherals controlled by an 80 MHz ARM? Cortex?-M3 processor and integral flash for code and data.The ADC on the ADuCM322 provides 12-bit, 1 MSPS data acquisition on up to 16 input balls. Additionally, chip temperature and supply voltages can be measured.The ADC input voltage range is 0 V to VREF. A sequencer is provided, which allows a user to select a set of ADC channels to measure in sequence without software involvement during the sequence. The sequence can optionally repeat automatically at a user selectable rate. Up to eight VDACs are provided with output ranges that are programmable to one of two voltage ranges.The ADuCM322 can be configured so that the digital and analog outputs retain their output voltages through a watchdog or software reset sequence. Thus, a product can remain functional even while the ADuCM322 is resetting itself.The ADuCM322 has a low power ARM Cortex-M3 processor and a 32-bit RISC machine that offers up to 100 MIPS peak performance. Also integrated on-chip are 2 ? 128 kB Flash/EE memory blocks and 32 kB of SRAM. The flash comprises two separate 128 kB blocks supporting execution from one flash block and simultaneous writing/erasing of the other flash block.The ADuCM322 operates from an on-chip oscillator or a 16 MHz external crystal and a PLL at 80 MHz. This clock can optionally be divided down to reduce current consumption. Additional low power modes can be set via software. In normal operating mode, the ADuCM322 digital core consumes about 300 ?A per MHz.The device includes an MDIO interface capable of operating at up to 4 MHz. The capability to simultaneously execute from one flash block and write/erase the other flash block makes the ADuCM322 ideal for 10G, 40G, and 100G optical applications. In addition, the nonerasable kernel code plus flags in user flash provide assistance by allowing user code to robustly switch between the two blocks of user flash code and data spaces.The ADuCM322 integrates a range of on-chip peripherals that can be configured under software control, as required in the application. These peripherals include 1 ? UART, 2 ? I2C, and 2 ? SPI serial input/output communication controllers, GPIO, 32-element PLA, three general-purpose timers, plus a wake-up timer and system watchdog timer. A 16-bit PWM with seven output channels is also provided.GPIO balls on the device power up in high impedance input mode. In output mode, the software chooses between open-drain mode and push-pull mode. The pull-up resistors can be disabled and enabled in software. In GPIO output mode, the inputs can remain enabled to monitor the balls. The GPIO balls can also be programmed to handle digital or analog peripheral signals; in such cases, the ball characteristics are matched to the specific requirement.A large support ecosystem is available for the ARM Cortex-M3 processor to ease product development of the ADuCM322. Access is via the ARM serial wire debug port (SW-DP). On-chip factory firmware supports in-circuit serial download via MDIO. These features are incorporated into a QuickStart? development system, supporting this precision analog microcontroller family.APPLICATIONS Optical networking
