TCS4525 5A, 3MHz Synchronous Step-Down DC-DC with I2C Compatible Interface DESCRIPTION The TCS4525 is a high-frequency, high-current synchronous step-down dc-dc converter optimized to supply the different sub systems of smart-phones, Tablets, and portable applications powered by one cell Li−Ion or three cell Alkaline/NiCd/NiMH batteries. The device is able to deliver up to 5A, with programmable output voltage from 0.6 V to 1.4V. The TCS4525 operates at 3-MHz fixed switching frequency which allows the use of small low cost inductors and capacitors. During light load conditions, the regulator includes a PFM mode to enhance light-load efficiency. The regulator transitions smoothly between PWM and PFM modes.
