SC81420Q

36V/2A, Automotive High Efficiency Buck Converter

The SC81420BQ and SC81420CQ are synchronous Buck converter with a wide input voltage range from 3V to 36V, providing 2A current capability options. The converter regulates the output voltage at customized voltage through setting the divider resistors. It also provides highly efficiency output current and fast loop response with current mode control. The SC81420BQ and SC81420CQ are specifically designed for automotive applications. The device integrates user-optional spread spectrum and QFN package, whose symmetrical pinout to optimize the EMI performance. In order to minimize solution size, two fixed switching frequency options are available to remove RT resistor. The switching frequency can also be synchronized to external clock through multiplexing EN/SYNC pin. For fixed frequency parts, a power good function is available by the PG pin. In addition, the device incorporates highly efficient PFM mode. If low output ripple is desired over full operational load range, FPWM mode option is also available. The SC81420BQ and SC81420CQ employ both peak current limit and valley current limit to help protect the device from overload as well as provides short-period heavy current capability. It also provides thermal shutdown, input UVLO, output short-circuit protection to enable systematical robust operation.
