Key Features
- Adjustable output current up to 700 mA set via external sense resistor for flexible LED string configurations
- Wide input voltage range up to 50 V supporting single and multi-string LED topologies from AC-DC or battery sources
- 5-pin TO-252 (DPAK) package with exposed thermal pad enabling efficient heat dissipation at high continuous drive currents
Applications
The TS19601CP5 is well suited for general illumination, architectural lighting, and automotive accent lighting applications requiring stable 700 mA current drive across varying supply voltages up to 50 V. Its adjustable current set point accommodates LED strings with 2 to 15 series LEDs driven from common AC-DC or 24 V industrial power rails. The TO-252 package with integrated thermal pad allows efficient heat spreading in cost-sensitive, space-constrained luminaire designs.

Frequently Asked Questions
What is the maximum LED drive current and input voltage rating of the TS19601CP5?
The TS19601CP5 supports a maximum LED drive current of 700 mA and operates from input voltages up to 50 V. These ratings allow it to drive 2 to 15 series-connected LEDs from common AC-DC adapters or 24 V industrial bus supplies, covering a broad range of general and architectural lighting applications.
How is the output current programmed on the TS19601CP5 LED driver?
LED drive current on the TS19601CP5 is set by an external sense resistor connected between the CS pin and ground. Using a 0.1 ohm resistor programs approximately 700 mA of output current, while higher resistance values proportionally reduce current, enabling designers to adjust LED brightness from 50 mA to 700 mA using a single resistor value change.
How does the TO-252 package of TS19601CP5 manage heat at full 700 mA load?
The 5-pin TO-252 (DPAK) package on the TS19601CP5 features an exposed thermal pad that transfers heat directly to a copper pour area on the PCB, enabling continuous 700 mA LED current drive without an external heatsink in most applications operating below 85°C ambient temperature. Adequate copper area of at least 1 square inch is recommended for optimal thermal performance.
