General Description
The APW8824 is a high efficiency monolithic synchro-
nous buck regulator. APW8824 operates with a constant
1.5MHz switching frequency and using the inductor cur-
rent as a controlled quantity in the current mode
architecture. The 2.7V to 5.5V input voltage range makes
the APW8824 ideally suited for single Li-Ion battery pow-
ered 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 ex-
ternal Schottky diode.
The APW8824 is available in TSOT-23-6A package

Ordering and Marking Information
Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).

Note 1: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only and functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.
