The TPS543A26T is a high-efficiency, 18V, 16A, synchronous buck converter employing an internally compensated, fixed-frequency advanced current mode (ACM) control architecture, which while always operating under FCCM, generates output voltages from 0.5V to 7V. The device is capable of providing high efficiency while operating at a switching frequency up to 2.2MHz, making the device an excellent choice for designs requiring a small design size. 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, two-wire remote sense, 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.

The TPS543A26T is available in a small 2.5mm × 4.5mm HotRod™ WQFN-FCRLF package.

TPS543B25TEVM — 동기 SWIFT™ 스텝다운 컨버터용 TPS543B25T 평가 모듈

TPS543B25TEVM은 TPS543B25T 통합 회로(IC)용 평가 모듈(EVM)입니다. TPS543B25T는 TEP(열 강화 패키징)를 갖춘 동기 스텝다운 컨버터로, 히트 싱크와 함께 사용할 때 열 성능을 개선하기 위해 표준 오버몰딩 IC의 상단 몰드 컴파운드를 제거합니다. EVM에는 로우 프로파일 외부 구성품과 컨버터 상단에 히트 싱크를 장착할 수 있는 스레드 구멍 2개가 있습니다. TPS543B25TEVM은 노출 다이 패키징을 모든 장착 히트 싱크와 함께 사용하여 다이 온도를 최소화하고, 열 경화를 줄이며, 특히 높은 (...)
