Description
The TPS63020DSJT is a power supply for products that use two- or three-cell alkaline, NiCd, or NiMH batteries, one-cell Li-ion or Li-polymer batteries, supercapacitors, or other supply rails. The device can handle output currents of up to 3 A. Batteries can be drained to below 2 volts when used. To achieve optimal efficiency, the buck-boost converter is based on a fixed frequency, pulse width modulation (PWM) controller with synchronous rectification. The converter enters power-save mode at low load currents to maintain high efficiency over a wide load current range. The converter can be forced to operate at a fixed switching frequency if the power saves feature is disabled. The maximum average current in the switches is usually limited to 4 A. The output voltage can be customizable or fixed on the chip using an external resistor divider. To save battery life, the converter can be turned off. The load is separated from the battery during the shutdown.
The TPS63020DSJT gadget works in a temperature range of –40°C to 85°C in the open air. The devices come in a 14-pin VSON package with dimensions of 3 mm x 4 mm (DSJ).
