LM25011, LM25011-Q1, LM25011A, LM25011A-Q1 42-V 2-A Constant On-Time Switching

Regulator With Adjustable Current Limit

1 Features

3 Description

The LM25011 constant on-time step-down switching

regulator features all the functions needed to

implement a low-cost, efficient, buck bias regulator

capable of supplying up to 2 A of load current. This

high-voltage regulator contains an N-Channel Buck

switch, a startup regulator, current limit detection, and

internal ripple control. The constant on-time

regulation principle requires no loop compensation,

results in fast load transient response, and simplifies

circuit implementation. The operating frequency

remains constant with line and load. The adjustable

valley current limit detection results in a smooth

transition from constant voltage to constant current

mode when current limit is reached, without the use

of current limit foldback. The PGD output indicates

the output voltage has increased to within 5% of the

expected regulation value. Additional features

include: Low output ripple, VIN under-voltage lock-

out, adjustable soft-start timing, thermal shutdown,

gate drive pre-charge, gate drive under-voltage lock-

out, and maximum duty cycle limit.
