BD9701FP - Simple Step-down Switching Regulators

General 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.

Key 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).
