Buck regulator for harsh environments
The part integrates a synchronous rectifier, which eliminates the external Schottky diode and improves efficiency at lower output voltages — a useful feature when the output is below 3.3V and the duty cycle is short.
1 MHz switching — inductor sizing trade-off
With a 1 MHz switching frequency, the TPS62110HPWP lets the designer use a smaller inductor (typically in the 4.7 µH to 10 µH range) compared to a 500 kHz part, which saves board area. The trade-off is higher switching losses and slightly more output ripple — the inductor value and output capacitor ESR need to be chosen to keep ripple within the load's tolerance.
Without that thermal land, the junction temperature rises quickly under full 1.5A load. The package is a 4.40 mm wide PowerTSSOP with 0.65 mm pitch — standard for a 16-pin HTSSOP footprint.
The base product number TPS62110 covers a family of fixed and adjustable output variants in different package options — the HPWP suffix specifically identifies the 16-HTSSOP tube-packaged adjustable-output version.
Sourcing and procurement posture
The active lifecycle status means supply is generally stable, but lead times can vary with factory loading and market demand.
