■General Description

The XC9101 series are step-up multiple current and voltage feedback

DC/DC controller ICs. Current sense, clock frequencies and amp

feedback gain can all be externally regulated.

■Features

ꢀStable Operations via Current & Voltage Multiple Feedback

ꢀUnlimited Options for Peripheral Selection

ꢀCurrent Protection Circuit

A stable power supply is possible with output currents of up to 1.5A.

With output voltage fixed internally, VOUT is selectable in 0.1V steps

within a 2.5V - 16.0V range ( 2.5%).

ꢀCeramic Capacitor Compatible

For output voltages outside this range, we recommend the FB version

which has a 0.9V internal reference voltage. Using this version, the

required output voltage can be set-up using 2 external resistors.

Switching frequencies can also be set-up externally within a range of

100~600 kHz and therefore frequencies suited to your particular

application can be selected.

With the current sense function, peak currents (which flow through

the driver transistor and the coil) can be controlled. Soft-start time can

be adjusted using external resistor and capacitor.

During shutdown (CE pin =L), consumption current can be reduced to

as little as 0.5µA (TYP.) or less.
