General Description
The LSP7706 is a high voltage, low dropout
current regulator for high power LED lighting.
The LSP can handle the maximum output
current up to 1.1Amp.
The output current
can also be varied by an external resistor.
The output sink current could be switched off
via OE pin. And the OE pin can also be used
to control PWM dimming function.
TO263-5L green package is available to
enhance the power dissipation of the driver.
Applications
High Power LED Driver
RGB Full Color Power LED driver
LCD Monitor/TV LED Backlight Driver
LED Lighting
LED Street Lamp / Table Lamp
The LSP7706 also features with build-in
thermal protection to prevent the chip from
over heat damage. The adequate thermal
pad in PCB area is required to control the
junction temperature below 125°C.
