3 Description
The TPS61376 is a high voltage non-synchronous
boost converter with input average current limit and
true load disconnect functions. The input average
current limit threshold can be programmed through
the ILIM pin from 0.1 A to 3.0 A. The isolation FET
between the VP and SW pin will completely cut off
the path between input and output when the device
is disabled. The TPS61376 has a wide input voltage
range from 2.9 V to 23 V and output voltage covers up
to 25 V.
The TPS61376 implements the peak current mode
with the adaptive off-time control topology. The device
works in PWM mode at moderate to heavy loads. At
the light load conditions, the device enters PFM mode
to maintain high efficiency over the entire load current
range.
The TPS61376 also integrates robust protection
features including output overvoltage protection,
cycle-by-cycle overcurrent protection and thermal
shutdown.
The TPS61376 offers a very small solution size with a
2.5-mm × 2.0-mm HotRod™ Lite VQFN package.
