GENERAL DESCRIPTION
FEATURES
The high frequency PWM operation also saves board space by reducing external component sizes. To improve efficiency, the feedback voltage is set to 200mV and 300mV, which reduces the power dissipation in the current 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 LP3322 High Efficiency: 88% 1.1MHzFixed-Frequency PWM Operation Maximum Output Voltage up to 36V Operating Range : 2.7V to 5.5V Shutdown Supply Current:<1uA Available in SOT23-6 Package Built-in 39V Over Voltage Protection Minimize the External Component RoHS Compliant and 100% Lead (Pb)-Free APPLICATIONS
