DD331
General Description
with four N-type MOSFETs and external resistors. The four output enable terminals are
designed to drive LED with PWM functions. The maximum voltage and current in LED
string are determined by specification of N-type MOSFET.
Features
◆
◆ Flexible in system design:
◆ Fast dimming frequency
◆ Supply voltage range: 5V ~ 18V
Applications
Package Types
SOP16, SSOP16
DD331 is a 4-channel LED pre-driver. It could provide constant-current to drive LED
Four independent LED output channels enable terminals, and current adjustment.
Maximum constant current output (ILED),
maximum sinking output voltage (VLED), and
minimum output voltage
are determined by the characteristic of N-type MOSFET
(determined by gate capacitance of MOSFET)
LED architectural or entertainment lighting
LED general or specialty illumination
LED backlighting applications
