The REF4132-Q1 device is a low temperature drift
(12 ppm/°C), low-power, high-precision CMOS voltage reference, featuring ±0.05% initial
accuracy, low operating current with power consumption less than 100µA. This device also offers
very low output noise of 15 µVp-p /V, which enables its ability to maintain
high signal integrity with high-resolution data converters in noise critical systems. Packaged in
the same SOT-23-5 package, REF4132-Q1 offers enhanced specifications and pin-to-pin replacement for
LM4128-Q1 and LM4132-Q1.
Stability and system reliability are further improved by the low output-voltage hysteresis of the device and low long-term output voltage drift. Furthermore, the small size and low operating current of the devices (100 µA) can benefit portable and battery-powered applications.
REF4132-Q1 is specified for the wide temperature range of −40°C to +125°C.

PMP23547 — GaN 式 8kW 三相圖騰柱功率因數校正和三相 LLC 參考設計
PMP23630 — 適用於 HVDC 30kW PSU 的資料中心參考設計
此參考設計為一款具備高電壓 DC (HVDC) 輸出功能的兩級高效率 30kW 電源供應器。第一級為以三相輸入來源供電的三階飛馳電容器功率因數校正 (PFC) 轉換器。透過 TMS320F28P650DK 高性能微控制器執行 PFC 控制。由於電感器中的倍頻效應，選擇了飛馳電容器拓撲結構而非更傳統的拓撲結構（例如 Vienna 整流器）。這種倍增效應可使得電感器體積更小且效率更高。PFC 後接兩個 Δ-Δ 連接的三相電感器-電感器-電容器 (LLC) 轉換器。其中一個 LLC 用於 +400V，另一個 LLC 用於 -400V。LLC 轉換器可配置為獨立電源供應器，或作為單一 800V (...)
