一,产品概述(General Description)

The JTMX6006 regulator is fixed frequency PWM Boost (step-up) LED
constant current driver, capable of driving Series 1W/3W/5W LED units with excellent line and load regulation. The regulator is simple to use because it
includes internal frequency compensation and a fixed-frequency oscillator

so that it requires a minimum number of external components to work.
The JTMX6006 could directly drive 16 Series 1W/3W LED units at VIN=24V .

requires a minimum number of external components to work.
The JTMX6005 could directly drive 11 Series 1W LED units at VIN>12V .
The PWM control circuit is able to adjust the duty ratio linearly from 0 to
90%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.

五,产品封装图 (Package)

Pin Number	Pin Name	Description
1	GND	Ground Pin.
2	EN	Enable Pin. Drive EN pin low to turn off the device, drive it high to turn it on. Floating is default high.
3	SW	Power Switch Output Pin (SW).
4	VIN	Supply Voltage Input Pin. JTMX6006 operates from a 5V to 32V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input.
5	FB	Feedback Pin (FB). The feedback threshold voltage is 0.22V.
