TPSM843320E is a highly efficient, small, and flexible synchronous step-down DC-DC converter in a MicroSiP power module package that is easy to use. The module operates up to 18V input with fixed-frequencies that are resistor adjustable by system designer. The embedded IC is internally compensated which reduces external components and design size. The integrated high-frequency capacitor reduces the transient peak at switching node.

The TPSM843320E module employs an internally compensated, fixed-frequency advanced current mode control. The device is capable of providing high efficiency while running at a switching frequency up to 2.2MHz. The fixed frequency controller can operate from 500kHz to 2.2MHz and can be synchronized to an external clock using the SYNC pin. Additional features include a high accuracy voltage reference, selectable soft-start times, monotonic start-up into prebiased outputs, selectable current limits, adjustable UVLO through the EN pin, and a full suite of fault protections.

TPSM843620EVM — TPSM843620 동기 벅 컨버터용 평가 모듈

TPSM843620 평가 모듈(EVM)은 최대 6A 출력을 공급하도록 설계된 동기식 벅 전원 모듈로, 정격 전압이 4V~18V입니다. 고압측 및 저압측 MOSFET은 게이트 드라이브 회로와 인덕터, 기본 패시브와 함께 TPSM843620 패키지 내부에 결합되어 있습니다. MOSFET의 드레인-소스 온 저항이 낮아 TPSM843620가 높은 효율을 달성할 수 있도록 하고 정격 출력 전류에서 접합부 온도를 낮게 유지해 줍니다. 고정 주파수 고급 전류 모드 제어를 통해 모듈을 외부 클록 소스에 동기화할 수 있습니다. 외부 분배기를 (...)
