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.

레퍼런스 디자인

PMP31247 — C2000™ MCU용 오토모티브 9W 듀얼 벅 컨버터 레퍼런스 설계

이 레퍼런스 설계는 공칭 12V 배터리에서 2개의 출력 전압 레일을 생성하는 C2000™ 마이크로컨트롤러용 오토모티브 전원 공급 장치입니다. LMR23630-Q1은 입력 전압을 조정된 3.3V 레일로 변환합니다. 첫 번째 출력에서 ​​공급되는 TPS628501-Q1은 1.2V 출력 레일을 생성합니다. 양쪽 컨버터 모두 FPWM(강제 펄스 폭 변조)에서 작동하여 출력 리플을 최소화하고 부하 과도 응답을 최적화합니다. 모든 테스트는 PMP31047 개정판 B 보드에서 수행되었습니다.
