APW 7101 operates with a constant 1.
5MHz switching frequency and using the inductor current as a controlled quantity in the current mode architecture.
The device is available in an adjustable version and fixed output voltages of 1.
5V and 1.
8V.
The 2.
5V to 5.
5V input voltage range makes the APW7101 ideally suited for single Li-Ion battery powered applications.
100% duty cycle provides low dropout operation, extending battery life in portable electrical devices.
The internally fixed 1.
5MHz operating frequency allows the use of small surface mount inductors and capacitors.
The synchronous switches included inside increase the efficiency and eliminate the need for an external Schottky diode.
Low output voltages are easily supported with the 0.
6V feedback reference voltage.
The APW7101 is available in a low profile SOT package for saving the printed circuit board area.
