(3) Stop sequences
Stop sequences are shown in Figure 4. AC VOLTAGE 0.0V DRAIN-GND VOUT-GND VUVLO1 VCHG2 VCC-GND_IC V V CHG1 UVLO2 OVER LOAD NORMAL LOAD 128ms IOUT SWITCHING A B C D E F Figure 4. Stop sequences timing chart A: Normal operation B: The input AC voltage is stopped. The DRAIN voltage starts to drop. C: If the DRAIN voltage drops below a certain voltage, it becomes MAX duty and over load protection operates. D: If the output voltage drops, the VCC pin voltage, too. And recharge operation is started. E: The recharge operation is stopped. F: If the DRAIN voltage drops below a certain voltage, the VCC pin voltage lowers below UVLO in order to stop recharge operation. www.rohm.com © 2017 ROHM Co., Ltd. All rights reserved. 8/21
