E522.3x - products for use in harsh environments
With the E522.3x chips, ELMOS introduces a new LED controller family. The
ICs are designed for input voltages between 5V and 55V and an output
voltage of up to 60V in boost mode, and they can be operated - depending on
the type - in single and/or dual LED chain mode.
With an ambient temperature range of -40 to +125 C, the ELMOS ICs are made
especially for use in harsh environments such as automotive conditions or
exterior lighting. Other fields of use are interior house lights and TFT
backlighting.
In addition to high robustness, the components offer a great variety in the
selection of circuit topologies, such as boost, SEPIC, buck-boost, and
buck. The switching frequency can be adjusted to up to 600kHz by means of
an external resistor or synchronized with other components in master-slave
configuration. Power consumption in sleep mode is only 8µA.
The versatility of the E522.3x controller family is completed by various
control and monitoring functions, e.g. protection against short-circuit,
overtemperature, overvoltage and undervoltage, and load break.
This IC family is supplied in the shape of single or dual controller in a
QFN32L5 package.
