Preliminary Datasheet

LP6482S

340KHz, 36V/2.5A Step-down Converter With Soft-Start

General Description

The LP6482S contains an independent 340KHz

constant frequency, current mode, PWM step-down

converters. The converter integrates a main switch

and a synchronous rectifier for high efficiency

without an external Schottky diode. The converter

can supply 2500mA of load current. The LP6482S

can also run at 90% duty cycle for low dropout

applications.

It

provides

fast

transient

response

and

cycle-by-cycle limit with current mode control. And

adjustable soft start prevents inrush current at turn

on and the supply current drops below 0.1uA in

shutdown mode.

The LP6482S is available in a SOP8 and ESOP8

package and is rated over the -40°C to 85°C

temperature range.
