The LMR23630-Q1 SIMPLE SWITCHER® is an easy-to-use 36-V, 3-A synchronous step-down regulator. With a wide input range from 4 V to 36 V, the device is suitable for various applications from industrial to automotive for power conditioning from unregulated sources. Peak-current-mode control is employed to achieve simple control-loop compensation and cycle-by-cycle current limiting. A quiescent current of 75 µA makes it suitable for battery powered systems. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes the external components. The device has option for constant frequency FPWM mode to achieve small output voltage ripple at light load. An extended family is available in 1-A (LMR23610-Q1), 1.5-A (LMR23615-Q1), and 2.5-A (LMR23625-Q1) load current options in pin-to-pin compatible package which allows simple, optimum PCB layout. A precision enable input allows simplification of regulator control and system power sequencing. Protection features include cycle-by-cycle current limit, hiccup-mode short-circuit protection, and thermal shutdown due to excessive power dissipation.

參考設計

PMP31247 — 適用於 C2000™ MCU 的車用 9-W 雙降壓轉換器參考設計

此參考設計是 C2000™ 微控制器的車用電源供應器，可從額定 12-V 電池產生兩個輸出電壓軌。LMR23630-Q1 將輸入電壓轉換為穩壓 3.3-V 電壓軌；由第一個輸出供應的 TPS628501-Q1 會產生 1.2-V 輸出軌。兩部轉換器皆以強制脈衝寬度調變 (FPWM) 運作，可將輸出漣波降到最低，並將負載暫態回應最佳化。所有測試都會在 PMP31047 修訂版 B 電路板上完成。
