LM43603 datasheet

Description

The LM43603 SIMPLE SWITCHER regulator is an easy to use synchronous step-down DC-DC converter capable of driving up to 3 A of load current from an input voltage ranging from 3.5 V to 36 V (42V abs max). The LM43603 provides exceptional efficiency, output accuracy and dropout voltage in a very small solution size.

An extended family is available in 0.5 A ,1 A and 2 A load current options in pin to pin compatible packages. Peak current mode control is employed to achieve simple control loop compensation and cycle-by-cycle current limiting. Optional features such as programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, extendable soft start, and tracking provide a flexible and easy to use platform for a wide range of applications.

LMR24210 datasheet

Description

The LMR24210 Synchronously Rectified Buck Converter features all required functions to implement a highly efficient and cost effective buck regulator. It is capable of supplying 1A to loads with an output voltage as low as 0.8V. Dual N-Channel synchronous MOSFET switches allow a low component count, thus reducing complexity and minimizing board size.

Different from most other COT regulators, the LMR24210 does not rely on output capacitor ESR for
stability, and is designed to work exceptionally well with ceramic and other very low ESR output
capacitors.
