The TPSM8F7x20 is a power-dense quad-channel buck power module designed to provide efficient and reliable power conversion for a wide output voltage range from 0.6V to 11V. The module integrates MOSFETs, inductor, and select capacitors to reduce board space and layout complexity. The module can be configured into both multiphase and multi-output rails by supporting 2, 3, and 4-phase stackability with interleaved phases. Under steady-state conditions the module operates in FCCM with a fixed-frequency that is resistor adjustable from 400kHz to 2.2MHz and synchronizable to an external clock.
TPSM8F7x20 module employs current mode control with internal and external compensation. Sequencing requirements are easily met with the external soft-start, active output discharge, adjustable EN, and power-good features. A full suite of protection features (output OV and UV, input UVLO, TSD, OC) are also included for robustness.

TPSM8F7620EVM — TPSM8F7620 評估模組
TIDA-011001 — 四通道、6A、0V 至 5V 可編程電源供應器參考設計
本參考設計提出一種高密度、四通道的數位控制可編程電源供應器，主要針對燒機與可靠度測試應用。此設計支援 12VDC 輸入匯流排，並提供四個獨立穩壓的輸出通道，每通道可在 0V 至 5V 範圍內調整，最大連續輸出電流為每通道 6A。
控制架構以 C2000™ 即時微控制器 (MCU) 為核心，用於執行 2P2Z (雙極點、雙零點) 數位補償器。16 位元、四通道 DAC 透過回饋接腳電流注入技術，動態調變降壓電源模組的輸出。此設計藉由內建低漂移 PGA 的 24 位元、16 通道 SAR ADC 同步擷取電流與電壓遙測數據，在全負載範圍內實現小於全刻度 ±0.005% 的負載調整率誤差。
