XC9101 series is Not Recommended for New Designs.
XC9101 Series PWM Controlled Step-Up DC/DC Controller ETR0403_006a ■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 0.
1V 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 using 2 external resistors.
Switching frequency can also be set externally within a range of 100 ~ 600 kHz and therefore a frequency 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.
