Block Descriptions

Block Name

Function

Description of Blocks

Reference

Reference voltage

The Reference generates the Reference Voltage.

Error Amplifier

Error amplifier

The Error Amplifier amplifies the difference between the feed

back voltage of the output voltage and the reference voltage.

TSD

Thermal shutdown protection

The TSD protects the device from overheating.

If the chip temperature (Tj) reaches ca. 175 °C (Typ),

the output is turned off.

OCP

Over current protection

The OCP protects the device from damage caused by over

current.

UVLO

Under voltage lock out

The UVLO prevents malfunction of the reset block in case of

very low output voltage.
