Supply QX2303 / springs core authorized agent genuine original price advantage

Overview QX2303 series is a high efficiency, low ripple high operating frequency of the PFM step-up DC-DC converter. QX2303 series requires only four per device, you can complete the transformation of low input battery voltage boost to the desired operating voltage, very suitable for portable section 1-4 applications where conventional batteries. Circuit uses a high-performance, low-power reference voltage circuit structure, while the introduction of amendments to technology in production to ensure the accuracy of the output voltage, high output and low temperature drift. QX2303 available SOT-23-3, SOT-23-5, SOT-89 package, SOT23-5 package built-EN-enabled client, you can control the working status of the converter, make it in the off state power, power minimize consumption characteristics of the maximum operating frequency:? 300KHz Output voltage:? 2.5V ~ 5.0V (step 0.1V) low starting voltage:? 0.9V (1mA) output accuracy:? better than ± 2.5% maximum efficiency:? 90 % Output Current:? more than 300mA (Vi = 2.5V, Vo = 3.3V) Low ripple and low noise applications range from 1 to 3 batteries in electronic equipment, such as:? electronic dictionaries, digital cameras, LED flashlight, LED lights, sphygmomanometer, MP3, remote control toys, wireless headphones, wireless mouse and keyboard, medical equipment, anti-lost, car alarm, battery charger, VCR, PDA and other handheld electronic devices
