TPS61050EVM-269 描述
The TPS61050EVM-269 facilitates evaluation of the TPS61050 1.2 A High Power White LED Driver IC in the BGA (YZG) package.
The TPS6105x device is based on a high-frequency synchronous-boost topology with constant current sink to drive single white LEDs. The device 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 μH inductors. To optimize overall efficiency, the device operates with only a 250 mV LED feedback voltage
