Single-chip Type with Built-in FET Switching Regulator Series Simple Step-down Switching Regulators with Built-in Power MOSFET BD9701F P/CP-V5/T/T-V5, BD9703FP/CP-V5/T/T-V5,BD9702CP-V5/T/T-V5 No.09027EBT01 ●Description The BD9701/BD9703/BD9702 are single-channel step-down switching regulator capable of PWM operation. The Pch MOS FET is built in for high efficiency in small load area.Lower electricity consumption of operating current 4mA (Typ) and stand-by current 0uA(Typ) is realized by adopting Bi-CMOS process. ●Features 1) Maximum switching current: 1.5A(BD9701/BD9703), 3A(BD9702) 2) Built-in Pch FET ensures high efficiency 3) Output voltage adjustable via external resistors 4) High switching frequency: 100kHz (BD9701), 300kHz(BD9703), 110kHz(BD9702) 5) Overcurrent and thermal shutdown protection circuits built in 6) ON/OFF control via STBY pin 7) Small surface mount TO252-5 package (only BD9701FP, BD9703FP) ●Applications TVs, printers, DVD players, projectors, gaming devices, PCs, car audio/navigation systems, ETCs, communication equipment, AV products, office equipment, industrial devices, and more. ●Line Up BD9701FP/CP-V5/T/T-V5 BD9703FP/CP-V5/T/T-V5 Output Current Input Voltage Switching Frequency External Synchronization Stand-by Function Operating Temperature Package T 100kHz (fixed) 1.5A 8 or Vo+3 ~ 36V 300kHz (fixed) × ○ -40 ~ +85℃ O252-5/TO220CP-V5/TO220FP-5/TO220FP-5 (V5) TO220CP-V5/TO220FP-5/TO220FP-5 (V5) BD9702CP-V5/T/T-V5 3.0A 110kHz (fixed) www.rohm.com © 2009 ROHM Co., Ltd.
