Preliminary Datasheet

LP6230C

1.0MHz,24V/2.0A High Performance, Boost Converter

General Description

The LP6320C is a 1MHz PWM boost switching

regulator designed for constant-voltage boost

applications. The LP6230C can drive a string of up to

30V. The LP6230C implements a constant frequency

1MHz PWM control scheme. The high frequency PWM

operation also saves board space by reducing external

component sizes. The LP6230C features automatic

shifting to pulse frequency modulation mode at light

loads.Highly integration and internal compensation

network minimizes as 6 external component counts.

Optimized operation frequency can meet the

requirement of small LC filters value and low operation

current with high efficiency. The LP6230C includes

under-voltage lockout, current limiting, and thermal

overload protection to prevent damage in the event of

an output overload. The LP6230A is available in a

small 8-pin MSOP8 package.
