General Description
The APS2415 is a high efficiency monolithic
synchronous buck regulator using a constant frequency,
current mode architecture. The device is available in an
adjustable version and fixed output voltages, such as
1.2V, 1.5V, 1.8V, etc. Supply current with no load is
300uA and drops to <1uA in shutdown. The 2.5V to
6.5V input voltage range makes the APS2415 ideally
suited for single Li-Ion, two to four AA battery-powered
applications. 100 duty cycle provides low dropout
operation, extending battery life in portable systems.
PWM pulse skipping mode operation provides very low
output ripple voltage for noise sensitive applications.
Switching frequency is internally set at 1.2MHz,
allowing the use of small surface mount inductors and
capacitors. The internal synchronous switch increases
efficiency and eliminates the need for an external
Schottky diode. Low output voltages are easily
supported with the 0.6V feedback reference voltage. The
APS2415 is available in a small SOT package.
