XC9101Series

ETR0403_003

PWM Controlled Step-Up DC/DC Controllers

■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.

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

With output voltage fixed internally, VOUT is selectable in 100mV increments within a 2.5V ~ 16.0V range (±2.5%).

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 ~ 600kHz 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.
