BM1R00147F
高效率、低待機功耗、支援連續模式 二次側同步整流控制IC

BM1R00147F是用於二次測輸出段的同步整流控制器。內建超低功耗的高精度分流穩壓器,可大幅度減少待機時的功耗。分流穩壓器由完全獨立晶片構成,因此即使在High Side使用時,也可作為GND基準工作。此外,連續模式工作時,可以不輸入一次側開關同步信號進行動作,有助於進一步節省空間。工作電源電壓範圍廣,為2.7V~32V,可應對各種輸出的應用。採用高耐壓120V處理器,可直接監視漏極電壓。

    • Evaluation Board - BM3G007MUV-EVK-001
    • This evaluation board outputs an isolated voltage of 12 V from an input of 90 Vac to 264 Vac, and the maximum output current is 8.3 A. It was developed mainly as a power supply for adapters. The average efficiency is 90.7% when VIN = 230V. The BM3G007MUV is GaN HEMT (650 V 70 mΩ), with integrated driver and protection circuitry. QR controllers for AC/DC power supplies use BM1Q021FJ.

    • Evaluation Board - BM1R00147F-EVK-001
    • This evaluation board has provided the secondary-side synchronous rectification circuit using BM1R00147F. This evaluation board assumes that the primary side controller of insulated type with PWM flyback converter operates in DCM and set to 5V for output voltage. The secondary-side MOSFET uses ROHM’s RX1L16BGN. The secondary-side MOSFET can be located on High Side. (When the secondary-side MOSFET is located on Low Side, see “User’s Guide BM1R00147F-EVK-002 (No.60UG023E)”.)
