Texas Instruments TPS61052EVM-269

The TPS61052EVM-269 facilitates evaluation of the TPS61052 1.2A high power white LED driver 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.

The TPS6105x device not only operates as a regulated current source, but also as a standard voltage-boost regulator. This additional operating mode can be useful to supply other high-power devices in the system, such as a hands-free audio power amplifier, or any other component requiring a supply voltage higher than the battery voltage (refer to TPS61052).
