The new product is fabricated with the latest 0.13µm analog process technology and integrates various power supplies units—charger, power path [1], Buck Converters, LDO Regulators—and the LED Driver required for mobile devices in one chip. Housed in a compact 7mmx7mm QFN (Quad Flat No-lead) package with excellent thermal performance, “TC7734FTG” will contribute to space-saving and device downsizing.

Key Features of the New Product

Integrating thermal detect function, over current limitation function, and LED open/ short detection ensures safe operation.

Individual setting of output voltages, power sequencing, and many other functions can be programmed through I2C with user programmable eFuse to meet diverse platforms needs.
Programming settings, status, and fault conditions can be read in the registers that enable the system processors to make decisions necessary for optimized operation.

Applications

Mobile devices, such as smartphones, tablets, handheld medical devices, industrial PDA, barcode readers
