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.
