2 ch DC/DC Converter IC with Synchronous Rectification Datasheet

The MB39C011A is a two-channel DC/DC converter IC suitable for down-conversion that utilizes synchronous rectification and pulse width modulation (PWM). The MB39C011A can operate over a wide range of power supply voltages (4.5 V to 17 V), making it optimal as a built-in power supply in digital audio visual equipment and various other electronic devices.

FEATUREs
■ Wide range of power supply voltages: 4.5 V to 17 V
■ Supports high frequency operation: 2.0 MHz (Max)
■ Supports synchronous rectification method (CH1, CH2)
■ An arbitrary output voltage can be configured using an external resistance.
■ Built-in standby function: 0 A (Typ)
■ Low current consumption: 2.2 mA (Typ, At quiescence)
■ Built-in soft-start circuit that can control each channel separately independent of the load
■ Built-in timer latch type short-circuit protection circuit (shares the soft-start capacitor)
■ Built-in totem pole type output stage for external P-ch/N-ch MOS FET devices
■ Package : TSSOP-16-pin
