BD9701T fiche technique
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.
