AS1015中文资料300KHz, 23V/5A Step-Down Converter数据手册Anisem规格书

描述 Description

The AS1015 is a voltage mode, step-down DC-DC converter that is designed to meet 5A output current and utilizes PWM control scheme that switches with 300KHz fixed frequency. This device includes a voltage reference source, error amplifier, oscillation circuit, P-channel MOSFET etc. The input voltage range of AS1015 is from 3.6V to 23V, and provides adjustable output voltage range from 0.8V to VIN for customers in application.

The AS1015 provides an enable function that can be controlled by external logic signal and excellent regulation during line or load transient due to the internal compensation. Other features of thermal protection, current limit and short circuit protection are also included. Due to the low Drain-Source resistance of internal power MOSFET, the AS1015 provides a high efficiency step-down application. It can also operate with a maximum duty cycle of 100% for use in low drop-out conditions.
