LT3990EMSE Demo Board | 6.5V ≤ VIN ≤ 60V, VOUT = 5V @ 350mA, Integrated Diodes
Analog Devices Inc.
Demonstration circuit 1471 is a monolithic step-down DC/DC switching regulator featuring the LT3990. The switching frequency is adjustable up to 2.2MHz. The demo circuit is designed for 5V, 350mA output from a 6.5V to 62V input. The wide input range of the LT3990 allows a variety of input sources including automotive batteries and 24V industrial supplies. Low ripple Burst Mode increases the efficiency at the light load while keeping the output ripple below 5mV in a typical application. The part is in shutdown when the EN pin is low and active when the pin is high. The threshold of the EN pin is accurate at 1V when VIN is above 4.2V. Adding a resistor divider from VIN to EN can program the LT3990 to regulate the output only when VIN is above a desired voltage. The catch diode and boost diode are integrated to reduce the components count and solution size. The circuit consumes only 2.5μA of quiescent current.

DC3080A-KIT
Analog Devices Inc.
The LTC4126-ADJ is a low-power wireless single-cell Li-Ion battery charger with an integrated step-down DC/DC regulator. The step-down regulator is a low-noise multimode charge pump which is powered from the battery and provides a regulated 1.2V at the output. The switching frequency is set to either 50kHz or 75kHz depending on the mode to keep any switching noise out of the audible range.The constant-current constant-voltage Li-Ion battery charger has automatic recharge, automatic termination by safety timer, and battery temperature monitoring via an NTC pin. Charge current is programmable from 1mA to 50mA via an external resistor. Undervoltage protection disconnects the battery from all loads when the battery voltage is below 3.0V.The small package and minimal external component count make the LTC4126-ADJ and its variants suitable for hearing aid applications and other low power portable devices.

The ADP2114 is a highly versatile, synchronous step-down, switching regulator that can be configured to satisfy a wide range of customer point of load requirements. The two PWM channels can be configured to deliver independent outputs at 2 A and 2 A (or 3 A/1 A) or can be configured as a single interleaved output capable of delivering 4 A. The two PWM channels are 180? phase shifted to reduce input ripple current and reduce input capacitance.The ADP2114 provides high efficiency performance at full loads, enabling high switching frequencies at up to 1.2 MHz. At light loads, the ADP2114 can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode to reduce EMI.The device is designed with an optimized gate slew rate to reduce ENI emissions, allowing the device to supply sensitive, high performance signal chain applications. The frequency can be set to 300 kHz, 600 kHz and 1.2 MHz and can be synchronized to an external clock signal, minimizing the system noise between converters. The bidirectional synchronization pin is also configurable as a 90? out-of-phase output clock, providing the possibility for a stackable multiphase power solution.The ADP2114 input voltage range is from 2.75 V to 5.5 V, and it converts to fixed outputs of 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V that can be set independently for each channel using external resistors. Using a resistor divider, it is also possible to set the output voltage as low as 0.6 V. The ADP2114 operates over the ?40?C to +125?C junction temperature range.ApplicationsPoint-of-load regulationTelecom and networking systemsConsumer electronicsIndustrial and InstrumentationMedical
