com January 16, 2008 LM20124 4A, 1MHz PowerWise® Synchronous Buck Regulator General Description The LM20124 is a full featured 1 MHz synchronous buck regulator capable of delivering up to 4A 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.
95V to 5.
5V 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 ad...
