LM25010

42V, 1.0A Step-Down Switching Regulator

General Description

Features

n Wide 6V to 42V Input Voltage Range

n Valley Current Limiting At 1.25A

The LM25010 features all the functions needed to implement

a low cost, efficient, buck regulator capable of supplying in

excess of 1A load current. This high voltage regulator inte-

grates an N-Channel Buck Switch, and is available in ther-

mally enhanced LLP-10 and TSSOP-14EP packages. The

constant on-time regulation scheme requires no loop com-

pensation resulting in fast load transient response and sim-

plified circuit implementation. The operating frequency re-

mains constant with line and load variations due to the

inverse relationship between the input voltage and the on-

time. The valley current limit detection is set at 1.25A. Addi-

tional features include: VCC under-voltage lock-out, thermal

shutdown, gate drive under-voltage lock-out, and maximum

duty cycle limiter.

n Programmable Switching Frequency Up To 1 MHz

n Integrated N-Channel Buck Switch

n Integrated High Voltage Bias Regulator

n No Loop Compensation Required

n Ultra-Fast Transient Response

n Nearly Constant Operating Frequency With Line and

Load Variations

n Adjustable Output Voltage

n 2.5V, 2% Feedback Reference

n Programmable Soft-Start

n Thermal shutdown

Typical Applications

Non-Isolated Telecommunications Regulator

Secondary Side Post Regulator

n Power SUpply for Automotive Electronics

Package

n LLP-10 (4 mm x 4 mm)

n TSSOP-14EP

n Both Packages Have Exposed Thermal Pad For

Improved Heat Dissipation

Basic Step-Down Regulator
