2 Order this document µa40/d µ The µa40 is a switching regulator subsystem, consisting of a temperature compensated voltage reference, controlledduty cycle oscillator with an active current limit circuit, comparator, highcurrent and highvoltage output switch, capable of. A and 40 V, pinnedout power diode and an uncommitted operational amplifier, which can be powered up or down independent of the IC supply. The switching output can drive external NPN or PNP transistors when voltages greater the 40 V, or currents in excess of. A, are required. ome of the features are widesupply voltage range, low standby current, high efficiency and low drift. The µa40 is available in commercial (0 to 0 C), and automotive (40 to C) temperature ranges. ome of the applications include use in stepup, stepdown, and inverting regulators, with extremely good results obtained in battery operated systems.

In practice, the calculated value will need to be increased due to the capacitor s equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly effect the line and load regulation. ee Application Note AN90 for further information 6 MOTOROLA ANALOG IC DEVICE DATA
