SC2442H - High Performance Wide Input Range Dual Synchronous Buck Controller

Download the SC2442H datasheet PDF. This datasheet also covers the SC2442 variant, as both devices belong to the same high performance wide input range dual synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

General Description

SC2442 and SC2442H are high performance dual buck converter controllers that can be configured for a variety of synchronous buck applications where efficiency is most important.

Both converters are synchronized to prevent beat frequencies.

Key Features

  • include: bootstrapping for high side drive supplies, asynchronous mode start up, power up sequencing to prevent latchups, individual soft start for each convertor, bootstrapped drivers for high side N-channel MOSFETs, input side current sensing, dual mode current limit with hiccup, enable and external frequency synchronization. The SC2442 operates over the range of 4.75V to 30V and SC2442H operates over the range of 4.75V to 36V. Typical.

SC2442/H High Performance Wide Input Range Dual Synchronous Buck Controller POWER MANAGEMENT Description SC2442 and SC2442H are high performance dual buck converter controllers that can be configured for a variety of synchronous buck applications where efficiency is most important. Both converters are synchronized to prevent beat frequencies. The dual buck converters are also operated out of phase reducing input ripple, allowing for fewer input capacitors. High frequency operation up to 1.1 MHz reduces the size of output inductors and capacitors. The controller has separate power pins for both VCC and GND to improve noise immunity. The VCC supplies can be regulated to 7V using an external PNP transistor.
