Product Summary

The TPS61050DRCR is a 1.2-A high power white LED driver 2-MHz synchronous boost converter with I2C compatible interface. The TPS61050DRCR is based on a high-frequency synchronous-boost topology with constant current sink to drive single white LEDs. The TPS61050DRCR uses an inductive fixed-frequency PWM control scheme using small external components, minimizing input ripple current. The 2-MHz switching frequency allows the use of small and low profile 2.2-mH inductors. To optimize overall efficiency, the TPS61050DRCR operates with only a 250 mV LED feedback voltage.
