3peak incorporated TPP00031 | Demoboard TPP00031

Beschreibung

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 and protection features. The constant on-time control scheme helps to improve fast transient response. 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 opera
