LP6205S Datasheet, PDF (1/5 Pages) Lowpower Semiconductor inc – 1.3V Start-up Input Voltage

Preliminary Datasheet
LP6205S
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.
