BD9701FP-E2 Electronic IC Chips Simple Step-down Switching Regulators

Single-chip Type with Built-in FET Switching Regulator Series

Simple Step-down Switching Regulators with Built-in Power MOSFET

BD9701FP/CP-V5/T/T-V5, BD9703FP/CP-V5/T/T-V5,BD9702CP-V5/T/T-V5

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.

Absolute Maximum Ratings (Ta＝25℃)

*1 Without external heat sink, the power dissipation reduces by 6.4mW/℃ over 25℃.

*2 Without external heat sink, the power dissipation reduces by 16.0mW/℃ over 25℃.

Reduced by 160mW/℃, when mounted on Infinity size heatsink.
