E522.32/34
Features
General Description
E522.32 and E522.34 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.

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. The phase shift
of 180° between channels essentially reduces EMI. De-
vices are available as 2-channel with spread spectrum
oscillators (E522.32) and as 2- channel without spread
spectrum (E522.34) versions to optimize size and ef-
fort of the application. Multiple control- and monitor-
ing functions, e.g. short- and open load detection, over-
temperature shutdown and undervoltage lockout are
implemented.
Advanced In-System Diagnostic (e.g. GND loss,
output-overload and highside-feedback
diagnostics)
