1 / 5 page Advanced Power Electronics Corp. FEATURES DESCRIPTION Input Voltage : 1.2V to 12V Low Quiescent Current : 17uA (typ.) Low Saturation Voltage : 200mV Typical at 300mA 350mA Typical Switching Current Limiting High Output Voltage : up to 34V Low Profile SOT-23-5L Pb-Free Packaging Halogen Free Product Data and specifications subject to change without notice TYPICAL APPLICATION 20130108V1.1 APE1910 STEP-UP PFM DC/DC CONVERTER 1 The APE1910 is a Pulse Frequency Modulation (PFM) DC/DC converter. It is Low quiescent current 30uA and shutdown current less 1uA. The APE1910 feature a wide input voltage. The operating voltage is ranged from 1.2V to 12V. It also feature low quiescent current, switching current limiting, low temperature coefficient. Smaller package size and fewer tiny external components are required in the application to save space and lower cost. APE1910 is available in SOT-23-5L C1 4.7uF/25V APE1910 SW GND FB EN VIN L1 22uH' 1 2 C3 4.7u/50V Vout=30V R2 200K Vout=VFB x (1 + R3/R2) VIN=5V R1 100K VFB=1.23V, R2 suggest 100K~300K C2 option D1 B140 1 2 R3 4.7M Figure 2.
