ST1CC40DR Description

Short technical summary and product information.

The ST1CC40DR from STMicroelectronics is a DC-DC step-down (buck) regulator specifically designed for LED driver applications. It delivers a continuous output current of 3A from a 3V input with a switching frequency of 850kHz. The regulator features a single output and includes internal switches, simplifying the external component count. The device is rated for an operating temperature range of -40°C to 150°C (junction temperature), making it suitable for demanding environments.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the ST1CC40DR is ideal for space-constrained applications. The manufacturer recommends it for use in lighting and signage systems. The device is RoHS3 compliant, REACH unaffected, and has an MSL of 1 for unlimited moisture sensitivity.

 

With its high switching frequency, the ST1CC40DR allows for the use of smaller external inductors and capacitors, reducing overall solution size. The buck topology efficiently steps down the input voltage to drive LEDs with constant current control.
