SLVSHB5A October 2024 – November 2024 TPS61287
PRODUCTION DATA
The TPS61287 is designed for output voltage up to 25V with the 20A switch current capability. The TPS61287 operates at a quasi-constant frequency pulse-width modulation (PWM) in moderate to heavy load condition. At light load, the converter can operate in either Auto PFM mode or Forced PWM mode, depending on the mode selected. The Auto PFM mode provides high efficiency over the entire load range, while the Forced PWM mode can avoid the acoustic noise as the switching frequency is fixed. The converter uses the adaptive constant on-time valley current control scheme, which provides excellent transient line and load response with minimal output capacitance. The TPS61287 can work with different inductor and output capacitor combinations by external loop compensation.
