s DESCRIPTION
MB3776A is a PWM system switching regulator controller. Because of its low operating supply voltage and power-
down, the MB3776A is ideal for use in DC/DC converters for battery-powered portable equipment.
s FEATURES
• Wide supply voltage range: (2 V to 15 V)
• Wide oscillation frequency range, high-frequency oscillation: (10 kHz to 500 kHz)
• Push-pull output. Drive current set with external resistor
• Bulit-in idle period circuit
• Internally set error amplifier gain, few external components
• Bulit-in power-down function
