Description

General part information

LM20143-Q1 Series

The LM20143 devices are full featured PowerWise™ adjustable frequency synchronous buck regulators capable of delivering up to 3 A of continuous output current. The current mode control loop can be compensated to be stable with virtually any type of output capacitor. For most cases, compensating the device only requires two external components, providing maximum flexibility and ease of use. The device is optimized to work over the input voltage range of 2.95 V to 5.5 V, making it suited for a wide variety of low voltage systems.

The device features internal over voltage protection (OVP) and over current protection (OCP) circuits for increased system reliability. A precision enable pin and integrated UVLO allows the turn-on of the device to be tightly controlled and sequenced. Start-up inrush currents are limited by both an internally fixed and externally adjustable Soft-Start circuit. Fault detection and supply sequencing is possible with the integrated power good circuit.

The frequency of this device can be adjusted from 500 kHz to 1.5 MHz by connecting an external resistor from the RT pin to ground.
