Description
General part information
TPS65266-1 Series
The TPS65266-1 incorporates 3 channels of high-efficiency synchronous buck converter for applications operating off the adaptor or battery with input voltage lower than 6 V.
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 PSM mode for a reduction on the input power supplied to the system. Cycle-by-cycle overcurrent limiting with hiccup mode limits MOSFET power dissipation in short circuit or overloading fault conditions.
The TPS65266-1 features a power-good supervisor circuit that monitors all converter outputs. The PGOOD pin is asserted after the output voltages in each channel are in regulation and sequencing is done.
