Part Number:TPS92691
Requirement:
1. Dimming mode and PWM dimming, 30V~60V input, output 57V2A (MAX, 1.8a is also ok)
2. PWM dimming frequency of 120kHz,Dtuty= about 35%.
This requires buck-boost IC with dimming function.
If there is no such dimming IC, is there simple buck-boost controller with higher voltage pressure (does LM5118 be Ok for this application?).
