Overview

The TPP00031/2 is a 300-mA output, synchronous, stepdown, switching converter with internal power MOSFETs.

The TPP00031/2 series integrates power transistors with internal soft-start, compensation, and protection features. The constant on-time control scheme helps to improve fast transient response without the need of a compensation network. The TPP00031/2 offers a very compact solution to achieve a 300-mA continuous output current over a wide input supply range, with excellent load and line regulation.

The device has an internal low-voltage internal regulator voltage with minimal supply voltage as low as 4.5 V. The internal regulator voltage can be supplied with output voltage via a diode path to further improve efficiency.

The TPP00031/2 series has different light load configurations supporting both forced-PWM mode (TPP00031) for fixed switching frequency and pulse-skip mode (TPP00032) to save quiescent current.

The device is available in the 8-pin ESOP8, DFN4X4-8, and DFN3X3-8 packages with the support of a wide operation ambient temperature range from −40 °C to 125 °C.
