DESCRIPTION

The A7545 is a current mode boost DC-DC converter. It is PWM circuitry with built-in 0.05Ω power MOSFET make this regulator highly power efficient. The internal compensation network also minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current.

The A7545 is available in PSOP8 package.
