(4) Start circuit
This IC enables low standby electric power and high-speed startup because it has a built-in start circuit. The consumption current after startup is only idling current ISTART3 (typ=10uA). The startup current flows from the DRAIN pin. r rte a St Figure 5. Start circuit ISTART2 ISTART1 ISTART3 Vsc VUVLO1 Figure 6. Start up current vs. VCC voltage www.rohm.com © 2017 ROHM Co., Ltd.
