Description
The GL5010 Series are VFM (Chopper) Step-up DC/DC
converter IC with ultra low supply current by CMOS
process.
Features
Small Number of External Components
±2.5% Output Voltage Accuracy
Low Ripple and Low Noise
Max. 0.9V Start-up Voltage
The GL5010 IC consists of an oscillator, a VFM control
(When the output current is 1 mA)
circuit, a driver transistor (Lx switch), a reference voltage
Typ. 80% Efficiency
unit, an error amplifier, resistors for voltage detection, and
Low Input Current (Typ. 10μA) at no load,
an Lx switch protection circuit. A low ripple, high efficiency
with 1.5V input)
step-up DC/DC converter can be constructed of this
GL5010 IC with only three external components, that is, an
inductor, a diode and a capacitor.
This GL5010 IC is suitable for use with battery-powered
instruments with low noise and ultra low supply current.
Application
Power source for battery-powered equipment.
Power source for cameras, camcorders, VCRs, PDAs, electronic data banks,and
hand-held communicationequipment.
Power source for appliances which require higher cell voltage than that of
batteries used in the appliances.
