TPS61088RHLR

The TPS61088 is a high-power density, fullyintegrated synchronous boost converter with a 11-mΩ
power switch and a 13-mΩ rectifier switch to provide
a high efficiency and small size solution in portable
systems. The TPS61088 has a wide input voltage
range from 2.7 V to 12 V to support applications with
single-cell or two-cell Lithium batteries. The device
has 10-A switch current capability and is capable of
providing an output voltage up to 12.6 V.
The TPS61088 uses adaptive constant off-time peak
current control topology to regulate the output voltage.
In moderate to heavy load condition, the TPS61088
works in pulse width modulation (PWM) mode. In
light load condition, the device has two operation
modes selected by the MODE pin. One is the pulse
frequency modulation (PFM) mode to improve the
efficiency and another one is forced PWM mode to
avoid application problems caused by low switching
frequency. The switching frequency in PWM mode is
adjustable, ranging from 200 kHz to 2.2 MHz by an
external resistor. The TPS61088 also implements a
programmable soft-start function and an adjustable
switching peak current limit function. In addition, the
device provides 13.2-V output overvoltage protection,
cycle-by-cycle overcurrent protection, and thermal
shutdown protection.
The TPS61088 is available in a 4.50-mm × 3.50-mm
20-pin VQFN package.
