PWM Controlled, Step-Up DC/DC Controller
The XC9101series 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 and output voltage is selectable in 0.1V steps within a 2.2V - 16.0V (+-2.5% accuracy) range (internal). 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 type).
Switching frequencies can be regulated externally within a range of 100 ~600 kHz and therefore frequencies suited to your particular application are selectable.
Further, the drive transistor's current limit can be applied via the current sense functionand soft-start times can be regulated by the external resistors and capacitors.
During shutdown (CE pin =L), consumption current can be reduced to as little as 0.5μA or less.
