The XC9301/02 series are 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 0.1V steps within a 2.4V ~ 6.0V ( ± 2.5%
accuracy) range and switching frequency is set at 180kHz or 300KHz.
The XC9302 series switches from PWM to PFM control during light loads
and the series offers high efficiencies from light loads through to large
output currents.
Soft-start time is internally set to 10 msec 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.
Input Voltage Range : 2.0V ~ 10V
Output Voltage Range : 2.4V ~ 6.0V ( ± 2.5% accuracy)
(selectable in 0.1V steps)
Oscillation Frequency : 180KHz, 300KHz ( ± 15% accuracy)
Output Current
: more than 250mA (VIN=2.4V,
VOUT=3.3V)
Efficiency
: 81% (typ) at 5.0V, 78% (typ) at 3.3V
