Buck DC-DC converter integrates power MOSFETs for optimized power efficiency

Mouser now stocks the Texas Instruments (TI) TPS65266 triple synchronous step-down converters. The device incorporate three channels of high-efficiency synchronous buck converter for applications operating off the adaptor or battery with input voltage lower than 6.5V. The buck DC-DC converter integrates power MOSFETs for optimized power efficiency and reduces external component counts. The peak current mode control simplifies the compensation and fast transient response. A high clock frequency allows smaller and low-value inductors and capacitors. External compensation supports optimized loop compensation and fast transient response. In light load condition, the buck converter operates in FCC mode for a reduction in noise susceptibility and RF interference. Cycle-by-cycle overcurrent limiting with hiccup mode limits MOSFET power dissipation in short circuit or over-loading fault conditions.
