4 CH BUCK LED Driver for Car-Brake-Light
Product ID: PT16922
The PT16922 is designed to operate as a constant-current source for car brake and tail light which is adopted in buck topology. Max 4-channels output can be driven more LEDs in automotive 12V system. 4 controlled current generators specifically designed to supply LED arrays. The LED current can be externally programmed. The change of working mode between brake and tail can be realized by the external brake signal. The current of each channel is up to 250mA in Brake-Mode, while it will be 15mA in Tail-Mode.
• ESD: ±4KV (HBM)& ±400V(MM)
• Input voltage: 6V~30V
• Integrated 40V power DMOS
• Programmable frequency: 100KHz~1MHz
• Brake-current and tail-current can be changed by external resistor individually.
• The brake-current and tail-current’s tolerance is ±3% between the CH to CH
• Programmable rise/fall time of switch
• Thermal shutdown protection& temperature compensation function
• LED open & short protection
• Output short protection
• Input over voltage protection
• LED brake “on” response time less than 10ms
