TPS61050EVM-269概述
电源管理IC开发工具 TPS61050EVM-269
The 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.
