A7530A Datasheet | AiT Semiconductor

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 parator, 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. The A7530A is available in SOT-23 and SOT-25 packages.
