MB3889規(guī)格書詳情
■ DESCRIPTION
The MB3889 is a symmetrical-phase type of two-channel, DC/DC converter IC using pulse width modulation (PWM) , incorporating an overcurrent protection circuit (requiring no current sense resistor) and an overvoltage protection circuit. Providing high output driving capabilities, the MB3889 is suitable for down-conversion.
■ FEATURES
? Built-in timer-latch overcurrent protection circuit (requiring no current sense resistor)
? Built-in timer-latch overvoltage protection circuit
? Synchronous rectification system providing high efficiency
? Power supply voltage range: 5.5 V to 18 V
? PWRGOOD terminals (open-drain) to output the protection status
? Symmetrical-phase system reducing the input capacitor loss
? Built-in channel control function
? Reference voltage: 3.5 V ± 1
? Error amplifier threshold voltage: 1.23 V ± 1 (0 °C to + 85 °C)
? Support for frequency setting using an external resistor (Frequency setting capacitor integrated)
? Oscillation frequency range: 100 kHz to 500 kHz
? Built-in circuit for load-independent soft-start and discharge control
? Built-in totem-pole output for Nch MOS FET
