General Description

Features

The XC9101/9102 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.

Stable Operations via Current & Voltage Multiple Feedback

Unlimited Options for Peripheral Selection

PWM/PFM Switching Control (XC9102)

A stable power supply is possible with output currents of up to 3A and

output voltage is selectable in 0.1V steps within a 2.2V - 16.0V

( 2.ꢀ5 accuracyꢁ range (internalꢁ. Further, a type which has a 0.9V

internal reference voltage and which allows output voltage to be set-up

freely via the external components is also available (FB typeꢁ.

Switching frequencies can be regulated externally within a range of

100 ~600 kHz and therefore frequencies suited to your particular

application are selectable.

Current Protection Circuit

Low Ripple Output Voltage during Light Loads (XC9102)

Ceramic Capacitor Compatible

The XC9102 series switches from PWM to current limited PFM control

during light loads and the series offers low ripple and high efficiencies

from light loads through to large output currents. Further, the drive

transistor's current limit can be applied via the current sense function

and soft-start times can be regulated by the external resistors and

capacitors.

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

as little as 0.ꢀµA or less.
