MAX630 Datasheet | Maxim Integrated

19-0915; Rev 2; 9/08 CMOS Micropower Step-Up Switching Regulator General Description Maxim’s MAX630 and MAX4193 CMOS DC-DC regulators are designed for simple, efficient, minimum-size DC-DC converter circuits in the 5mW to 5W range. The MAX630 and MAX4193 provide all control and power handling functions in a pact 8-pin package: a 1.31V bandgap reference, an oscillator, a voltage parator, and a 375mA N-channel output MOSFET. A parator 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...
