UMW R UMW XL1509 Features General Description n n n Wide 4.5V to 40V Input Voltage Range 3.3V,5V,12V, and adjustable versions Output Adjustable from 1.23V to 37V n n Maximum Duty Cycle 100% Minimum Drop Out 1.5V n n n Fixed 150KHz Switching Frequency 3A Constant Output Current Capability Internal Optimize Power Transistor High efficiency The XL1509 is a 150 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 3A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. n n n n n n n n Excellent line and load regulation TTL shutdown capability ON/OFF pin with hysteresis function The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is built inside. When second current limit function happens, the operation frequency will be reduced from 150KHz to 50KHz. An internal compensation block is built in to minimize external component count. Built in thermal shutdown function Built in current limit function Built in second current limit function Available in SOIC8 package Applications n n n n n LCD Monitor and LCD TV Digital Photo Frame Set-up Box ADSL Modem Telecom / Networking Equipment Figure1.
