SYNCHRONOUS PFM STEP-UP DC-DC CONVERTER

DESCRIPTION

FEATURES

The A7530A Series is a CMOS PFM-control

step-up switching regulator that mainly consists of a

reference voltage source, an oscillator, and a

comparator, enabling products with a low ripple

over a wide range, high efficiency, and high output

current. With the A7530A Series, a step-up

switching regulator can be configured by using an

external coil and capacitor. A protection circuit turns

off the built-in MOSFET when the voltage at the

CONT pin exceeds the limit to prevent it from being

damaged. This feature, along with the mini package

and low current consumption, makes the A7530A

Series ideal for applications such as the power

supply unit of portable equipment.
