ADVANCE PRODUCT INFORMATION - MAR 6, 2013

E522.31/33

Features

General Description

E522.31 and E522.33 are parts of a family of ﬁxed fre-

quency switch-mode high voltage LED power supplies

and controllers with high efﬁciency. Integrated high-

side sensing allows topologies related to GND (Boost-

to-GND or SEPIC) as well as related to input voltage

(Boost-to-battery or Buck-to-battery, particularly in

harsh automotive environments.

Switch-mode, single LED controller

5.0V to 55V input voltage range, up to 80V

boosted output voltage

Boost-, Boost-to-battery-, Buck-to-battery- or SEPIC-

topology

Constant current regulation implemented

Differential high-side sense up to 60V

High-frequency PWM dimming capability

10:1 Analog dimming capability for LED binning

Digital dimming up to 5000:1 at 100Hz PWM

Integrated softstart

The switching frequency is adjustable up to 600kHz by

an external resistor or can be synchronized in Master-

Slave conﬁgurations with other devices. Devices are

available with spread spectrum oscillators (E522.31)

and without spread spectrum (E522.33) versions to op-

timize size and effort of the application. Multiple con-

trol- and monitoring functions, e.g. short- and open

load detection, over-temperature shutdown and under-

voltage lockout are implemented.

Advanced In-System Diagnostic (e.g. GND loss,

output-overload and highside-feedback

diagnostics)

Very low sleep mode currents of typ. 8μA

Integrated automotive LDOs for 5V & 3.3V

AEC-Q100 Qualified

Junction temperature range -40°C to +150°C
