www.ti.com SNVS529G – OCTOBER 2007 – REVISED MARCH 2013 LM20144/LM20144Q 4A, PowerWise® Adjustable Frequency Synchronous Buck Regulator
Check for Samples: LM20144 FEATURES DESCRIPTION The LM20144 is a full featured adjustable frequency
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. 1 2 Available in AEC-Q100 Temperature Grade 1
