Product Overview
The TPS61088 is a Texas Instruments synchronous boost converter for Power_Management designs requiring step-up conversion from a 2.7 to 12 V input range to a 4.5 to 12.6 V output range. It provides 10 A switch current capability and uses adaptive constant off-time peak current control for output voltage regulation.
The device integrates low-resistance MOSFETs, with a high-side on-resistance of 13 mΩ typical and 18 mΩ maximum and a low-side on-resistance of 11 mΩ typical and 16.5 mΩ maximum at VCC = 6 V. Switching frequency is adjustable from 200 kHz to 2.2 MHz by an external resistor, with a 500 kHz typical condition specified for RFREQ = 301 kΩ.
TPS61088 is offered in a 20-pin VQFN (RHL) package with a 4.50 mm × 3.50 mm body. Recommended external components include 0.47 µH to 10 µH effective inductance, at least 10 µF input capacitance, and 6.8 µF to 1000 µF output capacitance. Integrated protection functions include output overvoltage protection, cycle-by-cycle overcurrent protection, and thermal shutdown.
