Switching Regulator Controller

(4 Channels plus High-Precision, High-Frequency Capabilities)

MB3785A

■ DESCRIPTION

The MB3785A is a PWM-based 4-channel switching regulator controller featuring high-precision, high-frequency

capabilities. All of the four channels of circuits allow their outputs to be set in three modes: step-down, step-up, and

inverted. The third and fourth channels are suited for DC motor speed control.

The triangular-wave oscillation circuit accepts a ceramic resonator, in addition to the standard method of oscillation

using an RC network.

■ FEATURES

• Wide range of operating power supply voltages: 4.5 V to 18 V

• Low current consumption: 6 mA [TYP] when operating10 µA or less during standby

• Built-in high-precision reference voltage generator: 2.50 V±1%

• Oscillation circuit

- Capable of high-frequency oscillation: 100 kHz to 1 MHz

- Also accepts a ceramic resonator.

• Wide input range of error amplifier: –0.2 V to V^CC–1.8 V

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