.Data Sheet.co.kr Rev.2.1_00 3-CHANNEL WHITE LED DRIVER IC (CHARGE PUMP IC WITH BUILT-IN CONSTANT-CURRENT CIRCUIT) S-8813 Series The S-8813 Series is a PFM control charge pump DC-DC converter with a built-in constant-current circuit, and was developed using CMOS technology. Its constant current output makes this series ideal as a power supply for current drive LEDs. The S-8813 Series Features three output channels and can drive three LEDs. This series is available in two types: a variable voltage type and a variable current setting resistance type. Moreover, since small ceramic capacitors can be used as external capacitors (pump capacitors, input capacitors, output capacitors), the S-8813 Series contributes to set miniaturization. - Features - PFM control CMOS charge pump - Built-in constant-current circuit - Power supply voltage: 2.7 V to 4.5 V - Output current value: A current variable is possible between 5.0 m A and 18 m A (At VIOUT1,2,3≤4.0 V, VIN=3.0 V) Variable voltage type and Variable current setting resistance type are available. - Terminal output current matching: ±1% max. - Built-in soft start circuit: 1.5 ms typ. - Constant current output pins: 3 channels, ±5% accuracy - Oscillation frequency: 600 k Hz typ. - ON/OFF function provided (During standby: 1 µA max.) - Ultra-small package: 10-Pin SON(B) - Lead-free products Applications - Power supply for white LED display backlights - Constant-current circuit - Cellular phones and PDAs using 1-cell lithium batteries - Power supply for flat panel displays Package Package Name 10-Pin SON(B) Package PE010-A Drawing Code Tape PE010-A Reel PE010-A Product Name List - S-881300CPE-IPATFG (Variable current setting resistance type) - S-881300BPE-IOQTFG (Variable voltage type) Seiko Instruments Inc.
