The TPS61372L is a full-integrated synchronous boost converter with the load disconnect built-in. The device supports output voltage up to 16V with a 3.8A current limit. The input voltage ranges from 2.5V to 5.5V supporting applications powered by a single-cell Lithium-ion battery or 5V bus.

The TPS61372L uses the peak current mode with the adaptive off-time control topology. The device works in PWM operation of 1.5 MHz at moderate-to-heavy loads. At the light load conditions, the device can be configured in either auto PFM or forced PWM operation by the MODE pin connection. Auto PFM mode has the benefit of high efficiency at light load while forced PWM operation keeps the switching frequency constant across the whole load range. The TPS61372L has a soft start to minimize the inrush current during start-up. The TPS61372L features of the load disconnect during shut down and provides a output short protection of hiccup mode. In addition, the device implements output overvoltage and thermal shutdown protection. The TPS61372L delivers a small solution size with a 14-pin WQFN 2.5mm × 2.5mm package of 0.8mm height.
