Introduction

AI Translation

The MAx650 is a low-power fixed +5V output switching DC-DC converter designed for operation from very high negative input voltages. All control functions and a 120V, 250mA PNP transistor are contained in this device, reducing external components. A soft-start eliminates overshoot on turn on, and a Shutdown pin (SHDN) allows the output to be turned on and off. In addition, peak current limiting is provided on the PNP output. The MAx650 features user-controllable operating frequency and a separate low voltage detector with adjustable hysteresis for monitoring the supply voltage. It can be set to trip at any negative voltage with a simple voltage divider. The MAx650 is available in an A version with ±5% output voltage tolerance and a B version with ±10% tolerance.
