AUR9703数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The AUR9703 is a high efficiency step-down
DC-DC voltage converter. The chip operation is
optimized using constant frequency, peak-current
mode architecture with built-in synchronous power
MOSFET switchers and internal compensators to
reduce external part counts. It is automatically
switching between the normal PWM mode and LDO
mode to offer improved system power efficiency
covering a wide range of loading conditions.
The oscillator and timing capacitors are all built-in
providing an internal switching frequency of 1.5MHz
that allows the use of small surface mount inductors
and capacitors for portable product implementations.
Additional features included Soft Start (SS), Under
Voltage Lock Out (UVLO), and Thermal Shutdown
Detection (TSD) to provide reliable product
applications.
The device is available in adjustable output voltage
versions ranging from 1V to 3.3V, and is able to
deliver up to 800mA.
The AUR9703 is available in TSOT-23-5 package.
