一,产品概述(General Description)

The JTMX8913 is a monolithic high voltage switching regulator with PFM
that is specifically designed to operate from a 24V~80V DC supply.
The JTMX8913 is a high efficiency LED driver switching regulator. The LED string is driven at DC constant current rather than constant voltage, thus providing constant current output and enhanced reliability.
二.产品特点(Features)

Wide 24V to 80V Input Voltage Range
0.2V current sense voltage reference.
Directly drive 3~8 series LED.
Excellent line and load regulation.
High efficiency up to 96%.
Internal optimize power HV-MOSFET.
Built in thermal shutdown function.
Built in UVLO function.
Built in current limiting function.
Built in LED open & short protection.
Built in soft-start circuit.
Available in TO252-5L package.
三,应用范围 (Applications)

EBIKE LED Lighting
LED Lighting & LED LAMP
General purpose lighting
