Therefore, a VDD of more than 2.0V is recommended when VDD is supplied from VIN or other power sources. *2 : Although the IC's switching operations start from a VIN of 0.9V, the IC's power supply pin (VDD) and output voltage monitor pin (FB1) should be connected to VOUT1. With operations from VIN=0.9V, the 2nd channel's (output 2) EN2 pin should be set to chip disable. Once output voltage VOUT1 is more than 2.0V, the EN2 pin should be set to chip enable. *3 : Please be careful not to exceed the breakdown voltage level of the external components. *4 : EFFI={ [ (Output voltage) × (Output current) ] / [ (Input voltage) × (Input current) ] } ×100 Unless otherwise stated, VDD=EN1=PWM1=3.0V, EN2=PWM2=GND, EXT2=OPEN, FB2=OPEN, VIN=1.8V (FOSC=180kHz) Ta=25℃ Ta=25℃ Ta=25℃ NOTE: |
