Frequently asked questions
Can SRK1000ATR be used in a 5V output USB charger?
Yes. The 3.75V minimum supply lets it operate from a 5V USB bus, and the adaptive control maintains synchronous rectification efficiency at the low output voltage where a Schottky diode would drop 0.4-0.5V. The part is listed for USB power applications.
