(Note 2) If mounted on a standard ROHM PCB (PCB size: 54mm x 62mm x 1.6mm), reduce by 13.12mW/C (Ta 25C). Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum rating Recommended Operating Range Parameter Symbol Range Unit Rectified Voltage Range VRECT 0 to 17.4 V AC1,AC2 Input Peak Voltage VAC1,VAC2 17.4 V Range ADDET Input Voltage VADDET 15.0 V (Note 3) OUT Terminal Voltage VOUT 5.0 to 12.0 V VCC Voltage Range VCC 2.5 to 3.0 V VCCPD Voltage Range VCCPD 2.5 to 3.0 V Capacitance between RECT-GND CRECT Min 20 F (Note 3) Supported VOUT is up to 10V. www .rohm.co.jp 2016 ROHM Co., Ltd.
