S-8363

S-8363 Series www.ablicinc.com © ABLIC Inc., 2010 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM / PFM SWITCHABLE SWITCHING REGULATOR Rev.2.0_02 The S-8363 Series is a CMOS step-up switching regulator which consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a current limit circuit, and a start-up circuit. Due to the operation of the PWM / PFM switching control, pulses are skipped under the light load operation and the S-8363 Series prevents decrease in efficiency caused by IC’s operating current. The S-8363 Series is capable of start-up from 0.9 V (IOUT = 1 mA) by the start-up circuit, and is suitable for applications which use one dry cell. The output voltage is freely settable from 1.8 V to 5.0 V by external parts. Ceramic capacitors can be used for output capacitor. Small packages SNT-6A and SOT-23-6 enable high-density mounting.  Features  Low operation voltage  Oscillation frequency  Input voltage range ...
