分享资料个
The ZXLD1374 is an LED driver converter IC with integrated
1.5A low side switch to drive high current LEDs. It is a multitopology
converter enabling it to efficiently control the
current through series connected LEDs. The multi-topology
enables it to operate in Buck, Boost and Buck-boost
configurations.
The 60V capability coupled with its multi-topology capability
enables it to be used in a wide range of applications and
drive in excess of 16 LEDs in series.
The ZXLD1374 is a modified hysteretic converter using a
patent pending control scheme providing high output current
accuracy in all three topologies. High accuracy dimming is
achieved through DC control and high frequency PWM
control.
The ZXLD1374 uses two pins for fault diagnosis. A flag
output highlights a fault, while the multi-level status pin gives
further information on the exact fault.
