1) Not subject to production test, specified by design.
2) Exposure to those absolute maximum ratings for extended periods of time (t > 10s) may affect device reliability
3) ESD susceptibility HBM according to EIA/JESD 22-A 114B (1.5kΩ,100pF).
Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.

Module Oscillator
7 Module Oscillator
7.1 Description
The oscillator turns on the power switch with a constant frequency while the buck regulating circuit turns the power
transistor off in every cycle with an appropriate time gap depending on the output and input voltage.
The internal sawtooth signal used for the PWM generation has an amplitude proportional to the input supply
voltage (feedforward).
The turn-on frequency can optionally be set externally via the ’SYNC’ pin using a TTL compatible input signal. In
this case the synchronization of the PWM-on signal refers to the falling edge of the ’SYNC’-pin input signal. In case
the synchronization to an external clock signal is not needed the ’SYNC’ pin should be connected to GND.
Leaving pin SYNC open or short-circuiting it to GND leads to normal operation with the internal switching
frequency.
