My customer is evaluating LM3409HV-Q1 for LED lighting source on HUD
application. As you know, Short time battery voltage drop at engine
restart after idling-stop(Cranking)must be mediate under real usage.
The customer is asking about such capability of LM3409HV-Q1.
Below is Vin(Battery voltage) profile at cranking.
PS) Output is just 1 LED, around 3.4V/1A.
1. I wonder LM3409HV-Q1 could work correctly during Vin voltage drop and after that?
2. I concern VCC Regulator driving which is defined on the DS(Vin > 9V, 0 < Icc < 20mA).
Is it no problem during Vin voltage drop?
