GENERAL 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.
The package is available in a standard SOP-8L.
