TPS61050YZGR Description

Short technical summary and product information.

The Texas Instruments TPS61050YZGR is a high-power white LED driver designed for applications such as camera flash in cell phones and smartphones. It utilizes a 2-MHz synchronous boost topology with constant current sink capability, capable of driving single white LEDs up to 1200 mA.

 

This device operates with a fixed-frequency PWM control scheme, allowing for small external components and minimizing input ripple current. The 2-MHz switching frequency enables the use of small, low-profile 2.2-μH inductors. For optimal efficiency, it operates with a low 250-mV LED feedback voltage. The TPS61050YZGR can function as a regulated current source or a standard voltage boost regulator, offering output voltages of 4.5 V, 5 V, and 5.25 V.

 

Flexibility is provided through an I2C-compatible interface for programming LED current or output voltage. It includes features like an integrated LED turn-on safety timer, zero latency TX-masking input for flash synchronization, and LED disconnect during shutdown to minimize leakage current. The device is available in a 12-pin NanoFree™ (CSP) and 10-pin QFN packaging, with this specific part in a 12-DSBGA package. It operates within a temperature range of -40°C to 85°C.
