The TPS56837H and TPS56837HA are high-efficiency, easy-to-use, synchronous buck converters with wide input voltage range of 4.5V to 28V. The devices support up to 8A continuous output current at output voltages between 4V and 22V, and support 5V, 9V, 15V, 20V dynamic output change for USB Power Delivery (USB PD) application.
The TPS56837H and TPS56837HA use D-CAP3 control mode to provide fast transient response, good line and load regulation, no requirement for external compensation, and support low equivalent series resistance (ESR) output capacitors like MLCC.
The TPS56837H and TPS56837HA operate at Eco-mode to attain high efficiency at light load with fixed 500kHz switching frequency and three selectable current limit through MODE pin configuration. The TPS56837H and TPS56837HA have adjustable soft-start time by the SS pin capacitor configuration.
The TPS56837H and TPS56837HA provide complete non-latched OV, UV, OC, OT, and UVLO protections combined with power-good indicator features. TPS56837H supports output discharge function and TPS56837HA disables the function.
The TPS56837H and TPS56837HA are available in a 10-pin, 3.0mm × 3.0mm, HotRod QFN package, and the junction temperature is specified from –40°C to 150°C.

TPS56837HEVM — TPS56837H 評估模組
PMP41117 — 65W 雙埠 USB 電力傳輸充電器參考設計（採用自偏壓 GaN 返馳式轉換器）
此參考設計為搭載自偏壓氮化鎵 (GaN) 返馳的 65W 雙埠 USB PD 快充充電器。此設計可在 90VAC 至 264VAC 間提供 65W 全額定功率，並可滿足效率標準與規範，例如針對在 25%、50%、75%、100% 下之平均效率的 DoE Level VI 和 CoC V5 Tier 2 效率標準，同時也可達到低待機功耗。AC-DC 級返馳轉換器 UCG28826 具有 VCC 自偏壓，並可免除對附屬線圈及相關 VCC 整流器電路的需求，進而簡化電路。DC-DC 級降壓轉換器 TPS56837HA 切換頻率以 500kHz 運作，可進一步將降壓級尺寸縮減至最小，產生每立方公分 (...)
