SLVSCM8D May 2015 – August 2021 TPS61088
The TPS61088 is designed for outputting voltage up to 12.6 V with 10-A switch current capability to deliver more than 30-W power. The TPS61088 operates at a quasi-constant frequency pulse-width modulation (PWM) in moderate-to-heavy load condition. In light load condition, the converter can either operate in PFM mode or in forced PWM mode according to the mode selection. The PFM mode brings high efficiency over entire load range, but PWM mode can avoid the acoustic noise as the switching frequency is fixed. The converter uses the adaptive constant off-time peak current control scheme, which provides excellent transient line and load response with minimal output capacitance. The TPS61088 can work with different inductor and output capacitor combination by external loop compensation. It also supports adjustable switching frequency ranging from 200 kHz to 2.2 MHz.
