XC9301 series
The XC9301 series is a step-up/down DC/DC converter controller ICs with fast, low ON resistance drivers built-in. A versatile, large output current, step-up/down DC/DC converter can be realised using only 4 basic external components - transistors, coils, diodes and capacitors.
Output voltage is selectable in 100mV steps within a 2.4V ~ 6.0V ( ± 2.5% accuracy) range and switching frequency is set at 180kHz or 300KHz. The XC9301 series switches in fixed frequency PWM control and offers high efficiencies for larger output currents. Soft-start time is internally set to 10msec which offers protection against rush currents when the power is switched on and also against voltage overshoot. During shutdown (CE pin = L), consumption current can be reduced to as little as 0.5μA or less.
Features:
- Input Voltage Range: 2.0V ~ 10V
- Output Voltage Range: 2.4V ~ 6.0V
