XA2100 Series Step-up DC-DC Converter
XA2100 Series is a PFM Step-up DC/DC
converter IC with low supply current by
CMOS
process. High frequency noise that occurs during
switching is reduced by using advanced circuit
designed, output
voltage is programmable in
0.1V steps between 2.0~7.0V and maximum
frequency is 100KHz(Typ.). A low ripple, high
efficiency step-up DC/DC converter can be
constructed of XA2100X xx with only three
external components. Also available is a
CE(chip enable) function that reduce power
dissipation
During shut-down mode.
XA2100Xxx is suitable for use with
battery-powered instruments with low noise and
low supply current.
Features
Low input current:6µA(Type); Low ripple and low noise;
Operating
voltage range:0.9V~6.5V; Output
voltage range:2.0V~7.0V(step 0.1V); Output
voltage accuracy:±2.5%; Output Current:if Vin=3.0V and Vout=3.3V,then
Iout=300mA; Low start
voltage:≤0.9V(at Iout=1mA...
