1 / 11 page Applications: Power source for battery-powered equipment Power source for wireless mouse, wireless keyboard, toys Power source for Cameras,camcorders, VCRs, PDAs Power source for hand-held communication equipment Descriptions: AMS1309 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 180 KHz(Typ.). A low ripple, high efficiency step-up DC/DC converter can be constructed of AMS1309 with only three external components. Also available is a CE(chip enable) function that reduce power dissipation During shut-down mode. AMS1309 is suitable for use with battery-powered instruments with low noise and low supply current. Featuers: 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=5.0V,then Iout=400mA Low start voltage: 0.9V(at Iout=1mA) Maximum oscillator frequency: 180KHz(Typ.) High Efficiency: 85%(Typ.) Packge:SOT23: SOT89 AMS1309 Advanced Monolithic Systems http://www.ams-semitech.com 1 |
