1 / 8 page  Preliminary Datasheet LP3301S LP3301S– 00 Version1.0 Datasheet Feb.-2010 www.lowpowersemi.com Page 1 of 8 1.2MHz,30V/1.4A High Performance, Boost Converter General Description The LP3301S is a 1.2MHz PWM boost switching regulator designed for constant-voltage boost applications. The LP3301S can drive a string of up to 30V. The LP3301S implements a constant frequency 1.2MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. To improve efficiency, the feedback voltage is set to 1250 mV, which reduces the power dissipation in the voltage setting resistor. Highly integration and internal compensation network minimizes as 5 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. Ordering Information LP3301S F: Pb-Free Package: B5: SOT23-5 B6: SOT23-6 Pin Configurations (TSOT23-6) (SOT23-5) Features High Efficiency: 95% 1.2MHzFixed-Frequency PWM Operation Maximum Output Voltage up to 30V Guaranteed 13V/400mA Output with 5V input Operating Range : 2.7V to 5.5V Shutdown Supply Current:<1uA Programmable Soft-star Available in SOT23-6/SOT23-5 Package Minimize the External Component RoHS Compliant and 100% Lead (Pb)-Free Applications Panel Bais Voltage supply OLED Backlight driver Notebook Computers Portable Applications MID/PTV Typical Application Circuit Marking information Please view website.
