GL5010

Gleam Power Management GL5010 100mA 100KHz DC-DC CONVERTOR BOPoOwSeTr MRaEnGagUeLmAenTtOR 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 ...
