ZX LD1371
60V HIGH ACCURACY BUCK/BOOS ST/BUCK-BO OOST LED DRIVER-CONT TROLLER
Descriptio on
The ZXLD137 71 is an LED driver contr roller IC for driving
external MOS FETs to drive high current LEDs. It is a multi-
Pin Assignme ents
TSSOP P-16EP

topology contr roller enabling it to efficiently y control the c current
through series connected EDs. The multi i-topology enab bles it
to operate in b buck, boost and d buck-boost co onfigurations.
The 60V capa ability coupled d with its mult i-topology cap pability
enables it to b be used in a wi de range of ap pplications and d drive
in excess of 15 5 LEDs in serie es.
The ZXLD137 71 is a modif fied hysteretic c controller us sing a
patent pending g control sche eme providing high output c current
accuracy in a all three mod des of operati ion. High acc curacy
