TPS61288RQQR Power Management ICs PMIC 11-VFQFN Package Boost Switching Regulator IC Step-Up
Adjustable 18V
Description for the TPS61288RQQR
The TPS61288RQQR employs peak current control topology with SOO modulation to regulate the output voltage. The device operates in the pulse width modulation (PWM) mode in moderate to heavy load condition. It automatically runs in the pulse frequency modulation (PFM) mode in light load and low duty cycle condition. SOO modulation realizes accurate regulation over wide load/VIN range while maintaining high efficiency and low output ripple. The switching frequency in the PWM mode is 500 kHz. The TPS61288 provides 19-V output overvoltage protection, cycle-by-cycle overcurrent protection, and thermal shutdown protection.
The TPS61288RQQR is available in a 2.5-mm × 3.0-mm QFN package.
