The TPS65266RHBT is a Synchronous Buck Converter incorporates 3 channels of high-efficiency. It is suitable 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. 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 overloading fault conditions. The TPS65266 features a power-good supervisor circuit that monitors all converter outputs.
● Dedicated enable and soft-start
● Accurate start-up timing control with enable pins discharge
● Forced continuous current (FCC) mode at light load
● Cycle-by-cycle current limiting with hiccup mode overcurrent protection
