The TPS61288 is designed for outputting voltage up to 18 V with the 15-A switch current capability. The TPS61288 operates at a quasi-constant frequency pulse-width modulation (PWM) in moderate to heavy load condition. In light load condition, the converter operates in PFM mode with single pulse. The PFM mode brings high efficiency over the entire load range. 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 TPS61288 can work with different inductor and output capacitor combinations by external loop compensation.
