描述 Description

■ DESCRIPTION
MB39A123 is a 6-channel DC/DC converter IC using pulse width modulation (PWM) , and it is suitable for up conversion, down conversion, and up/down conversion. MB39A123 is built in 6 channels into BCC-48++/LQFP-48P package and this IC can control and soft-start at each channel. MB39A123 is suitable for power supply of high performance potable instruments such as a digital still camera (DSC).■ FEATURES
• Supports for step-down with synchronous rectification (ch.1)
• Supports for step-down and up/down Zeta conversion (ch.2 to ch.4)
• Supports for step-up and up/down Sepic conversion (ch.5, ch.6)
• Negative voltage output (Inverting amplifier) (ch.4)
• Low voltage start-up (ch.5, ch.6) : 1.7 V
• Power supply voltage range : 2.5 V to 11 V
• Reference voltage : 2.0 V ± 1%
• Error amplifier reference voltage : 1.0 V ± 1% (ch.1) , 1.23 V ± 1% (ch.2 to ch.6)
• Oscillation frequency range : 200 kHz to 2.0 MHz
• Standby current : 0 µA (Typ)
• Built-in soft-start circuit independent of loads
• Built-in totem-pole type output for MOS FET
• Short-circuit detection capability by external signal (−INS terminal)
• Two types of packages (BCC-48 pin : 1 type, LQFP-48 pin : 1 type)■ APPLICATIONS
• Digital still camera(DSC)
• Digital video camera(DVC)
• Surveillance camera etc.
