MPQ4423C
DESCRIPTION
The MPQ4423C is a high-frequency, synchronous, rectified, step-down, switch-mode converter with integrated internal power MOSFETs. It offers a pact solution that can achieve up to 6A of peak output current (IOUT) across a wide 4V to 36V input voltage (VIN) range, with excellent load and line regulation.
Synchronous mode offers high efficiency across the entire IOUT load range. Peak current control mode provides fast transient response and improved loop stabilization.
Full protection features include over-current protection (OCP) with hiccup mode, output over-voltage protection (OVP), and thermal shutdown.
The MPQ4423C requires a minimal number of readily available, standard external ponents, and is available in a QFN-16 (3mmx4mm) package.
