MAX630CPA+

The MAX630CPA+ is a CMOS micropower step-up switching regulator in 8 pin DIP package. The CMOS DC to DC regulator is designed for simple, efficient, minimum-size DC to DC converter circuits in the 5mW to 5W range. The MAX630 provides all control and power handling function a 1.31V bandgap reference, an oscillator, a voltage comparator and a 375mA N-channel output MOSFET. A comparator is also provided for low-battery detection. Operating current is only 70μA and is nearly independent of output switch current or duty cycle. A logic-level input shuts down the regulator to less than 1μA quiescent current. Low-current operation ensures high efficiency even in low power battery-operated systems. The MAX630 is compatible with most battery voltages, operating from 2.0V to 16.5V. The device is pin compatible with the Raytheon bipolar circuits, RC4191/2/3, while providing significantly improved efficiency and low voltage operation.

• Supply voltage range is 2V to 16.5V
