Part Number:TPS92515HV
Hello E2E,
Our using EVM has about 2.5-msec startup time.
Conditions are follows;
- Vin is 24V.
- LEDs are 5 pieces in series. Vf = 3.05V/piece.
- ILED is 500mA.
At dumming from PWM-port, we want to reduce the startup time. I think that if prebias input for Vcc and IADJ that startup time to be early.
Question;
1) When Vin is not input, can I input 5V to Vcc?
2) When Vin input and PWM input Low, can I input 5V to Vcc and any voltage input to IADJ?
Regards,
ACGUY
