COMPACT, POWERFUL, EFFICIENT

The WTCP5V5A Temperature Controller delivers all the advantages of Pulse Width Modulated (PWM) control in a PCB-mounted package. The WTCP is compact and efficient, and usually does not require any additional heatsinking.

The WTCP temperature controller is perfectly suited for applications requiring high efficiency, low power dissipation, and high stability. Portable, airborne, and other space-constrained temperature control applications are ideal places to use the WTCP.

DESIGNED FOR EASY INTEGRATION

The WTCP5V5A can operate from a single 5 V power supply, or the WTCP and load can be driven from separate power supplies when even lower output current noise is required. The available WTCPEVAL evaluation circuit board includes everything needed to quickly configure the WTCP for a wide range of applications and load conditions. The on-board feedback loop parameter adjustment switches simplify tuning, and dramatically reduce your development time.

An OEM module board is also available, and can be preloaded at the factory with components fine-tuned for your application.

PRACTICAL FEATURES, ROBUST DESIGN

Thoughtfully designed features provide valuable benefits, and help ensure the long-term reliability of your application:

  • Separate heating- and cooling current limits protect the load from operational anomalies.
  • External passive components fine-tune the operating range for maximum control sensitivity and accuracy.
  • Versatile interface signals simplify integration of the WTCP into a wide range of applications.
  • Easy-to-use component selection calculator simplifies system design and configuration.
VALUABLE SAFETY FEATURES

Built-in safety features make the WTCP robust to real-world operating conditions: current limit, voltage limit. Long-term reliability means better up-time, fewer service calls, and more satisfied and successful customers.
