This family of devices offers design flexibility with a variety of user programmable functions, including; soft-start, UVLO, operating frequency, voltage feedforward, high-side current limit, and loop compensation. These devices are also synchronizable to an external supply. The TPS40060 and TPS40061 incorporate MOSFET gate drivers for external P-channel high-side and Nchannel synchronous rectifier (SR) MOSFETs. Gate drive logic incorporates anti-cross conduction circuitry to prevent simultaneous high-side and synchronous rectifier conduction.

Copyright © 2002–2013, Texas Instruments Incorporated TPS40060 TPS40061 SLUS543F – DECEMBER 2002 – REVISED JUNE 2013 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
