High Efficiency Boost DC/DC Regulator

General Description

The LP6205 is a current mode boost DC-DC

converter. Its

PWM

circuitry with built-in

0.3Ω,24V,1.5A Current power MOSFET makes this

converter highly power efficiently. Selectable high

switching frequency allows faster loop response and

easy filtering with a low noise output. The

non-inverting input its error amplifier is connected

to an internal 1.25V precision reference voltage.

Soft-Start time can be programmed with an external

capacitor, which sets the input current ramp rate.

Current mode control and external compensation

network make it easy and flexible to stabilize the

system.
