Description
General part information
TPS65270 Series
The TPS65270 is a monolithic, dual synchronous buck regulator with a wide operating input voltage that can operate in 5-V, 9-V, 12-V, or 15-V bus voltages and battery chemistries. The converters are designed to simplify its application while giving the designer the option to optimize their usage according to the target application.
The TPS65270 features a precision 0.8-V reference and can produce output voltages up to 15 V. Each converter features an enable pin that allows dedicated control of each channel that provides flexibility for power sequencing. Soft-start time in each channel can be adjusted by choosing different external capacitors. TPS65270 is also able to start up with a prebiased output. The converter begins switching when output voltage reaches the prebiased voltage.
Constant frequency peak current-mode control simplifies the compensation and provides fast transient response. Cycle-by-cycle overcurrent protection and hiccup mode operation limits MOSFET power dissipation in short-circuit or overloading fault conditions. Low-side reverse current protection also prevents excessive sinking current from damaging the converter.
