Descripción
- Circuit delivers a constant current of 2A to a multi-die IR LED device. The solar cell input requires very high efficiency, and a synchronous buck controller allows the use of a small FET at high frequency (800kHz) to achieve that efficiency. The LM78L05 provides a simple 5V rail for both the logic and FET drive of the LM2737 and the LMV321
