The TPS61288 is a high-power density, fully-integrated synchronous boost converter with a 6.5-mΩ power switch and a 8.5-mΩ rectifier switch to provide a high efficiency and small size solution in portable systems. The TPS61288 has a wide input voltage range from 2 V (2.4 V rising) to 18 V to support applications with single-cell or two-cell Lithium batteries. The device has 15-A switch current capability and is capable of providing an output voltage up to 18 V.

The TPS61288 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 TPS61288 is available in a 2.5-mm × 3.0-mm QFN package.

參考設計

PMP40909 — 3.3-V 至 4.2-V 輸入、12-V、60-W 峰值輸出功率升壓轉換器參考設計

此參考設計展示兩種以並聯方式連接兩個 TPS61288 裝置以支援高輸出功率的方法。其中一種方法是將 VIN、VOUT、FB 和 COMP 接腳直接連接在一起。由於兩個裝置在 COMP 接腳上共用相同電壓，因此兩個裝置的電感器尖峰電流在一般情況下為關閉。但考慮到最糟情況下的程序變化，單一裝置的輸出電流僅可為另一裝置的 50%。因此，此方法的最大平均功率在 3.3-V 至 4.2-V 輸入下約為 30 W，但數十毫秒內的峰值輸出功率可達 60 W。
