3 Description

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.
