Preliminary Datasheet

LP6222

High Efficiency Boost DC/DC Convertor

General Description

The LP6222 is a current mode boost DC-DC converter.

Its PWM circuitry with built-in 4.8A current power

MOSFET makes this converter highly power efficiently.

The LP6222 implements a constant frequency 1MHz

PWM control scheme. The high frequency PWM

operation also saves board space by reducing external

component sizes. The LP6222 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 LP6222 includes under-voltage lockout, current

limiting, and thermal overload protection to prevent

damage in the event of an output overload. The

LP6222 is available in a small SOT23-6&ESOP8

package.
