... ONE-SHOT Figure 1. Block Diagram _______________Detailed Description Operating Principle The MAX764/MAX765/MAX766 are BiCMOS, inverting, switch-mode power supplies that provide fixed outputs of -5V, -12V, and -15V, respectively; they can also be set to any desired output voltage using an external resistor divider. Their unique control scheme combines ...

... F 2) turns on again if the output is out of regulation. 20V The MAX764/MAX765/MAX766 limit the peak inductor current, which allows them to run in continuous-con- duction mode and maintain high efficiency with heavy INPUT loads. (See the photo Continuous Conduction at Full VOLTAGE (V) Current Limit in the Typical Operating Characteristics ...

... The input bypass capacitor, C1, reduces peak currents drawn from the voltage source and reduces the amount of noise at the voltage source caused by the switching action of the MAX764–MAX766. The input voltage source impedance determines the size of the capacitor required at the V+ input. As with the output filter capacitor, a low-ESR capacitor is highly recommended. For output currents up to 250mA, a 100µ ...
