The TPS63020DSJR from Texas Instruments is a high-efficiency single-inductor buck-boost converter with 4A integrated switches in a 14-pin VSON (4x3mm) package. It supports input voltages from 1.8V to 5.5V and adjustable output voltages from 1.2V to 5.5V, delivering up to 2A output current. With a fixed 2.4MHz switching frequency, synchronous rectification, power-save mode at light loads, and only 25\u00b5A quiescent current, it achieves up to 96% efficiency. Features include power-good output, load disconnect during shutdown, and comprehensive protection.<\/p>\n

It operates from 1.8V to 5.5V input and produces an adjustable 1.2V to 5.5V output at up to 2A. With a fixed 2.4MHz switching frequency, synchronous rectification, and power-save mode delivering only 25\u00b5A quiescent current, it achieves up to 96% efficiency. Features include power-good output, load disconnect during shutdown, and comprehensive protection, making it ideal for battery-powered and IoT applications.","working_principle":"The TPS63020DSJR uses a single-inductor non-inverting buck-boost topology with four integrated MOSFET switches controlled by an average current-mode PWM controller. When the input voltage is higher than the output, it operates as a buck converter using the high-side buck switch and low-side synchronous rectifier. When the input is lower than the output, it switches to boost mode using the high-side boost rectifier and low-side boost switch. Near the transition point, it alternates between buck and boost cycles using TI's Buck-Boost Overlap Control, which minimizes the number of classical buck-boost cycles (where all four switches are active) to maximize efficiency. The average current-mode control loop reconstructs the inductor current by measuring the high-side buck MOSFET current and uses a transconductance voltage error amplifier to regulate the output. Power-save mode activates at light loads, reducing switching frequency and quiescent current to 25\u00b5A. The dynamic current limit ramps up from 400mA during soft-start, reaching the nominal 4A limit only when the output voltage exceeds 1.2V, providing inherent short-circuit protection.","pin_description":"\n
