3 Description
The TPS63036 is a non-inverting buck-boost
converter able to provide a regulated output voltage
from an input supply that can be higher or lower than
the output voltage. The buck-boost converter is based
on a fixed frequency, pulse width modulation (PWM)
controller using synchronous rectification to obtain
maximum efficiency. At low load currents, the
converter enters power save mode to maintain high
efficiency over a wide load current range. The power
save mode can be disabled, forcing the converter to
operate at a fixed switching frequency.
The maximum average current in the switches is
limited to a typical value of 1000 mA. The output
voltage is programmable using an external resistor
divider.
The converter can be disabled to minimize battery
drain. During shutdown, the load is disconnected from
the supply.
2 Applications
• Battery voltage regulation (headsets and earbuds,
cameras, augmented reality glasses, electronic
and robotic toys, personal medical products)
• Wi-Fi® or Bluetooth® module supply (IP network
camera, wireless access point, single board
computer, portable POS, wireless sensors)
• LED/Laser supply (barcode scanner, laser
distance meter)
