Dual 1A, 1.5MHz PWM Step-down DC-DC Converter with OVP
AUR9717
General Description
The AUR9717 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 including Soft Start (SS), Under
Voltage Lock Out (UVLO), Input Over Voltage
Protection (IOVP) and Thermal Shutdown Detection
(TSD) are integrated 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 1A.
The AUR9717 is available in WDFN-3×3-10
package.
