LOW-NOISE 4.5A STEP-UP CURRENT MODE PWM CONVERTER

DESCRIPTION

FEATURES

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.



Adjustable Output up to 9V

Internal Fixed PWM frequency: 1MHz

Precision Feedback Reference Voltage: 0.6V (±2%)

Internal 0.05Ω, 4.5A, 12V Power MOSFET

Shutdown Current: 0.1μA

Over Temperature Protection

Over Voltage Protection

Adjustable Over Current Protection: 0.5A ~ 4.5A

Available in PSOP8 Package

The A7545 is available in PSOP8 package.
