E522.32/34
Features
General Description
E522.32 and E522.34 are part of a family of fixed fre-
quency switched-mode high voltage LED power sup-
plies and controllers with high efficiency. Integrated
high-side sensing allows topologies related to the sup-
ply input (Boost-to-Battery) or to GND (Boost-to-GND).
ÿ
ÿ
Dual switched-mode, PWM LED controller
5V to 55V input voltage range, up to 80V boosted
output voltage
ÿ
Boost-, SEPIC, Buck-Boost- or Buck Topology
supported
ÿ
ÿ
ÿ
Constant Current Regulation implemented
High-Precision Differential High-Side Sense up to 60V
High-Frequency PWM Dimming Capability for
constant LED Color
The devices are suitable for operation in boost-, buck-
boost-, SEPIC- and buck-topologies, particularly in
harsh automotive environments.
ÿ
ÿ
ÿ
Analog 10:1 Dimming Capability for LED Binning
Integrated Softstart
The constant switching frequency is adjustable up to
600kHz by an external resistor or can be synchronized
in Master-Slave configurations with other devices. The
phase shift of 180° between channels essentially re-
duces EMI.
Multiple control- and monitoring functions, e.g. short-
and open load detection, over-temperature shutdown
and under-voltage lockout are implemented.
Advanced Error Detection (e.g. Over-Voltage,
Open-Load Detection, different Shorts or GND Loss)
Integrated Automotive LDOs for 5V & 3.3V
AEC-Q100 Qualified
