Switching Regulator Controller

MB3817

■ DESCRIPTION

The MB3817 is a pulse width modulator (PWM) type switching regulator controller IC designed for low-voltage

and high-speed operation. This can be used in applications as down-conversion or down/up-conversion (Zeta

method).

With fewer external components and faster operating speed, the MB3817 enables reduction in power supply unit

size, making it ideal for use with internal power supplies in compact, high-performance portable devices.

■ FEATURES

• Wide range of operating power supply voltages: 2.5 V to 18 V

• Built-in high-precision reference voltage generator: 1.5 V ± 2%

• High speed operation is possible: Max. 500 kHz

• Wide input voltage range of error amplifier: 0 to V^CC– 0.9 V

• Built-in soft start function

• Built-in timer/latch-actuated short-circuiting protection circuit

• Totem-pole type output with adjustable on/off current (for PNP transistors)

• Built-in standby function

• Small package: SSOP-16P (FPT-16P-M05)

■ PACKAGE

16-pin Plastic SSOP

(FPT-16P-M05)
