S-8821

S-8821 Series www.sii-ic.com © SII Semiconductor Corporation, 2002-2017 VOLTAGE REGULATION BOOST CHARGE PUMP DC-DC CONVERTER Rev.5.1_02 The S-8821 series is a CMOS boost charge pump DC-DC converter with a voltage regulation function. The S-8821 series consists of an oscillation circuit, a controller, a reference voltage circuit, an error amplifier circuit, and an output switching transistor, and can regulate the output voltage by PFM control. Since small ceramic capacitors can be used for the pump capacitor, input capacitor, and output capacitor, the mounting area can be minimized.  Features PFM control CMOS boost charge pump Power supply voltage: Output voltage: Output voltage accuracy: Built-in soft start circuit: Output current Oscillation frequency: ON/OFF function: Lead-free, Sn 100%, halogen-free*1 1.6 to 5.0 V 2.5 to 5.5 V, selectable in 0.1 V steps. ±2 % max. 1.0 ms typ. 25 mA (VIN=(VOUT(S) × 0.80) V) 1.0 MHz typ. During standby: 1...
