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.
