MAX5033DUSA+

The MAX5033DUSA+ is a high efficiency, MAXPower step down DC to DC converter in 8 pin NSOIC package. This easy to use, high voltage converter operates from an input voltage range from 7.5V to 76V and consumes only 270μA quiescent current at no load. This pulse width modulated (PWM) converter operates at a fixed 125KHz switching frequency at heavy loads and automatically switches to pulse skipping mode to provide low quiescent current and high efficiency at light loads. The MAX5033 uses an internal low on-resistance, high voltage DMOS transistor to obtain high efficiency and reduce overall system cost. This device includes undervoltage lockout, cycle by cycle current limit, hicc-up mode, output short circuit protection and thermal shutdown. The MAX5033 delivers up to 500mA output current. The output current may be limited by maximum power dissipation capability of the package. External shutdown is included with 10μA shutdown current.
