The TPS62A2Ix-Q1 series are families of pin-to-pin compatible, high-efficiency, synchronous step-down DC-DC converters capable of delivering continuous output currents of 1A, 2A, 3A, and 4A. Using a constant on-time (COT) control topology, these devices provide fast transient response while maintaining quasi-fixed switching frequency operation during steady-state conditions.

To enhance loop performance, the devices offer 16 selectable internal compensation settings, enabling higher bandwidth and reducing output capacitance. Integrated low RDS(on) MOSFETs support continuous output up to 4A even at high ambient temperatures.

The switching frequency is adjustable from 1.5MHz to 4MHz and supports synchronization to an external clock. In PFM/PWM mode, the device automatically enters power-save mode at light loads to achieve high efficiency across the full load range. The device maintains the output voltage accuracy within ±0.8% in PWM mode for VOUT ≥ 0.5V. The soft-start feature provides controlled power-up and limits inrush current, while the soft-stop feature enables coordinated power-down sequencing.
