Preliminary Datasheet

LP3318

1MHz,36V/1.5A High Performance, Boost Converter

General Description

The LP3318 is a boost DC-DC converter. Its PWM

circuitry with built-in 1.5A current power MOSFET

makes this converter highly power efficiently. The

LP3318 implements a constant frequency 1MHz PWM

control scheme. The high frequency PWM operation

also saves board space by reducing external

component sizes. The LP3318 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 LP3318 includes under-voltage lockout, current

limiting, and thermal overload protection to prevent

damage in the event of an output overload. The

LP3318 is available in a small 5-pin SOT23-5

package.
