DC1920A: Demo Board for the LTC3553-2 - Micropower USB Power Manager with Li-Ion Charger, Always-On LDO and Buck Regulator

The LTC3129 is a high efficiency, 200mA buck-boost DC/DC converter with a wide VIN and VOUT range. It includes an accurate RUN pin threshold to allow predictable regulator turn-on and a maximum power point control (MPPC) capability that ensures maximum power extraction from non-ideal power sources such as photovoltaic panels.The LTC3129 employs an ultralow noise, 1.2MHz PWM switching architecture that minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Built-in loop compensation and soft-start simplify the design. For high efficiency operation at light loads, automatic Burst Mode operation can be selected, reducing the quiescent current to just 1.3?A.Additional features include a power good output, less than 10nA of shutdown current and thermal shutdown.The LTC3129 is available in thermally enhanced 3mm ? 3mm QFN and 16-lead MSOP packages. For fixed output voltage options, see the functionally equivalent LTC3129-1, which eliminates the need for an external feedback divider.

The LTC2378-20, LTC2377-20 and LTC2376-20 are 20‑bit, low power, low noise SAR ADCs with serial outputs that operate from a single 2.5V supply. The demo manual refers to the LTC2378-20 but applies to all parts in the family, the only difference being the maximum sample rate. The LTC2378-20 supports a ±5V fully differential input range with a 104dB SNR, consumes only 21mW and achieves ±2ppm INL max with no missing codes at 20 bits. The DC1925A demonstrates the DC and AC performance of the LTC2378-20 in conjunction with the DC590 QuikEval™ and DC890 PScope™ data collection boards. Use the DC590 to demonstrate DC performance such as peak-to-peak noise and DC linearity.

The LTM8053 is a 40VIN, 3.5A continuous, 6A peak step-down ?Module? (power module) regulator. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.4V to 40V, the LTM8053 / LTM8053- 1 supports an output voltage range of 0.97V to 15V and a switching frequency range of 200kHz to 3MHz, each set by a single resistor. Only the input and output filter capacitors are needed to finish the design. The LTM8053-1 can operate in forced continuous mode.The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8053 / LTM8053-1 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8053 / LTM8053-1 is RoHS compliant.APPLICATIONS Automotive Battery Regulation Power for Portable Products Distributed Supply Regulation Industrial Supplies Wall Transformer Regulation

The ADP2443 is synchronous step-down, dc-to-dc regulator with an integrated 98 m?, high-side power metal oxide semicon-ductor field effect transistor (MOSFET) and a 35 m?, synchronous rectifier MOSFET to provide a high efficiency solution in a compact 4 mm ? 4 mm LFCSP package. The regulators operate from an input voltage range of 4.5 V to 36 V. The output voltage can be adjusted down to 0.6 V and deliver up to 3 A of continuous current. The fast 50 ns minimum on time allows the regulators convert high input voltage to low output voltage at high frequency.The ADP2443 uses an emulated current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. The switching frequency of the ADP2443 can be programmed from 200 kHz to 1.8 MHz. The synchronization function allows the switching frequency be syn-chronized with an external clock to minimize the system noise.The ADP2443 targets high performance applications that require high efficiency and design flexibility. External compensation and an adjustable soft start function provide design flexibility. The power-good output and precision enable input provide simple and reliable power sequencing.Other key features include undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), short-circuit protection (SCP), and thermal shutdown (TSD).The ADP2443 operates over the ?40?C to +125?C operating junction temperature range and is available in a 24-lead, 4 mm ? 4 mm LFCSP package.Applications Intermediate power rail conversion Multicell battery powered systems Process control and industrial automation Healthcare and medical Networking and servers

The ADN4624 is a quad-channel, signal isolated, low voltage differential signaling (LVDS) buffer that operates at up to 2.5 Gbps with very low jitter. The device integrates Analog Devices, Inc., iCoupler? technology, enhanced for high speed operation to provide drop-in galvanic isolation of LVDS signal chains. AC coupling and/or level shifting to the LVDS receivers and from the LVDS drivers allows isolation of other high speed signals such as current mode logic (CML).The ADN4624 includes a refresh mechanism to monitor the input and output states and ensure they remain the same in the absence of data transitions (for example, at power-on).For lower power consumption and high speed operation with low jitter, the LVDS and isolator circuits rely on 1.8 V supplies. The ADN4624 is fully specified over a wide industrial temperature range and is available in a 28-lead, wide-body, finer pitch SOIC_W_FP package with 8.3 mm creepage and clearance (for 5.7 kV rms or 8 kVPEAK surge and impulse voltages and reinforced insulation at ac mains voltages) or 6 mm ? 6 mm LFCSP package with 1.27 mm creepage and clearance (for basic/functional isolation).APPLICATIONS Isolated video and imaging data Analog front-end isolation Data plane isolation Isolated high speed clock and data links Multi-gigabit serialization/deserialization (SERDES) Board-to-board optical replacement (for example, short reach fiber)
