The TPS65131-Q1 device is dual-output dc-dc converter generating a positive output voltage up to 15V and a negative output voltage down to –15V with output currents of typically 200mA, depending on input-voltage to output-voltage ratio. With a total efficiency up to 85%, the device is ideal for portable battery-powered equipment. The input-voltage range of 2.7V to 5.5V allows, for example, 3.3V and 5V rails to power the TPS65131-Q1 device. The TPS65131-Q1 device comes in a QFN-24 package with thermal pad and wettable flanks. Requiring few and small external components, the overall solution size can be small.

The converter operates with a fixed-frequency PWM control topology and, with power-save mode enabled, uses a pulse-skipping mode at light load currents. In operation, the typical overall device quiescent current is only 500µA. In shutdown, the device draws typically 0.2µA. Independent enable pins allow power-up and power-down sequencing for both outputs. The device has an internal current limit, overvoltage protection, and a thermal shutdown for highest reliability under fault conditions.

The TPS65131-Q1 device is qualified for automotive applications, according to AEC-Q100 temperature grade 2. The electrical characteristics are tested over –40°C to 125°C device junction temperature. This, combined with lowest shutdown currents, small solution size, package with thermal pad, plus good efficiency and protection features, targets automotive and industrial applications.

PMP9780 — 參考設計：使用 TPS65131-Q1 和電荷泵的雙極 TFT LCD 電源

此參考設計詳細說明顯示器電源電路，可為來源驅動器產生雙極電壓軌和為閘極驅動器產生其他電源。電荷泵用於為閘極驅動器產生電壓供應，使此設計易於實作。只使用一個 dc-dc 轉換器來產生四個電壓軌，進而將電感量降到最低，此電路就可實現小型設計尺寸。
