Does TI have new product roadmap that can meet below SPEC for automotive lighting?
Customer: SCI (TW, Tainan)
Application: Automotive lighting
Topology: Buck-Boost
Competition device: HV9910 ($ 18TWD). It already M/P
Vin range: 9V to 36Vdc
Vout Range: 7.2V(2 LED) or 10.8V (3 LED)
LED topoloty:2S2P or 3S2P
LED watts: 3W/pcs
Voltage stress Test item: 90V with 0.4S (SCI internal qualification process)
Original, we promoted and DIN the LM342x series to customer side. But it was fail to test item of voltage stress (90V with 0.4S, reliability test).
So do you have any idea to solve this? Or other suggestion of suited device?
