TPS61055YZGR TI LED Driver | 12-DSBGA | 2.5-5.5V Input, 1.5A Switch

Product Overview

The TPS61055YZGR from Texas Instruments is a high-efficiency, synchronous boost converter with an integrated 1.5A switch, specifically designed to drive up to five white LEDs in series for backlight applications. It operates from a single Li-Ion cell or 3-cell NiMH/NiCd battery input voltage range of 2.5V to 5.5V. The device features a 1.2MHz fixed switching frequency, allowing the use of small external components. The output voltage can be adjusted up to 24V via an external resistor divider. The TPS61055YZGR is available in a compact 12-pin DSBGA package (YGR), measuring 2.0mm x 2.0mm, ideal for space-constrained portable devices.
