一,产品概述(General Description)

The JTMX6003 regulator is fixed frequency PWM Boost (step-up) LED
constant current driver,capable of driving Series 1W 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 JTMX6003 could directly drive 6 Series 1W LED units at VIN>12V .
The JTMX6001 regulator is fixed frequency PWM Boost (step-up) LED
constant current driver,capable of driving Series 1W 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 JTMX6001 could directly drive 5~8 Series 1W LED units at VIN>12V .
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 95%. 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	EN	Enable Pin. Drive EN pin low to turn off the device, drive it high to turn it on. Floating is default high.
2	VIN	Supply Voltage Input Pin. JTMX6003 operates from a 3.6V to 24V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input.
3	FB	Feedback Pin (FB). The feedback threshold voltage is 0.22V.
4	NC	No Connected.
5,6	SW	Power Switch Output Pin (SW). Output is the switch node that supplies power to the output.
7,8	GND	Ground Pin.
