TCS4526
6A, 3MHz Synchronous Step-Down DC-DC with I2 C Compatible Interface
产品描述
The TCS4526 is a high-frequency, high-currentsynchronous step-down de-dc converter optimized tosupply the diferent sub systems of smart-phones.Tablets, and portable applications powered by one cellLi-lon or three cell Alkaline/NiCd/NiMH batteries. Thedevice is able to deliver up to 6A. with programmableoutput voltage from 0.6 V to 1.4V.
The TCS4526 operates at 3-MHz fixed switchingfrequency which allows the use of small low costinductors and capacitors. During light load conditions.the regulator includes a PFM mode to enhancelight-load eficiency. The regulator transitions smoothlybetween PWM and PFM modes.Synchronousrectification and automatic PWMPFM transitionsimprove overall efficiency.
The serial interface is compatible with FastStandardand High-Speed mode C specification allowingtransfers at up to 3.4 Mbps. This communicationinterface is used for dynamic voltage scaling withvoltage steps down to 6.25 mV, for reprogramming themode ofoperation(PFMor Forced PWM)ordisable/enabling the output voltage.
