APE1910

Advanced Power Electronics Corp. FEATURES 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 APE1910 STEP-UP PFM DC/DC CONVERTER DESCRIPTION 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 TYPICAL APPLICATION VIN=5V L1 1 22uH' D1 B140 R3 4.7M C1 VIN 4.7uF/25V R1 100K C2 option EN SW GND FB C3 4.7u/50V 2 1 2 Vout=30V APE1910 R2 200K Vout= VFB x (1 + R3/R2) VFB=1.23V, R2 suggest 100K~300K Figure 1.
