ABB CP630 Control Panel

Description

TPS63020DSJR is a high-efficiency, single-inductor buck-boost DC-DC converter designed for modern electronic systems requiring stable power under variable input conditions. It features a wide input voltage range of 1.8V to 5.5V, making it suitable for battery-powered devices and systems with fluctuating input voltages. The device delivers a programmable output voltage range of 1.2V to 5.5V, adjustable via an external resistor divider to match specific system power requirements.

In terms of performance, it offers high output current capability: up to 3A in buck mode and up to 2A in boost mode, with a typical switch current limit of 4A. Operating at a fixed 2.4 MHz switching frequency, it enables the use of smaller external components, reducing overall system size. It also boasts ultra-low quiescent current, with a typical value below 50 microamps, to minimize power draw in low-load or standby states.

Key protective features include over-temperature protection, over-voltage protection, and dynamic input current limiting, enhancing system reliability and preventing component damage. Housed in a compact 14-pin VSON package measuring 3mm x 4mm, it is optimized for SMD/SMT installation. Ideal applications include portable electronic devices, battery-powered equipment, IoT devices, and systems with wide input voltage variations, providing consistent, efficient power conversion with up to 95% efficiency.
