Beschreibung

The MPQ4456 is a high frequency step.down switching regulator with an integrated internal high.side high voltage power MOSFET. It provides 1 A output with current mode control for fast loop response and easy compensation.The wide 3.8V to 36V input range accommodates a variety of step.downapplications, including those in automotive systems. A 1204A operational quiescent current is suitable for use in battery.powered applications.Special controlled circuitry allows the MPQ4456 to maintain PWM operation at low output currents. This lowers noise by reducing the pulse skipping.By switching at 4MHz, the MPQ4456 prevents EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications.The MPQ4456 is available in thin 10.pin 3mm x 3mm TQFN package.
