Key Features
- Current-mode control enables precise parallel load sharing across multiple power supply modules
- Adjustable share threshold for flexible current balance tuning in multi-supply designs
- 8-PDIP through-hole package simplifies prototyping and retrofit into existing power control boards
Applications
The UCC39002P is designed for paralleled power supply systems where equal current sharing among redundant modules is required, such as N+1 redundant server power shelves and telecom rectifier stacks. Its adjustable threshold allows engineers to fine-tune current balance across modules operating from up to 14.25V input rails. It is equally suited for laboratory bench power systems and industrial power distribution units requiring hot-swap or redundancy capability.

Frequently Asked Questions
How does the UCC39002P achieve balanced current sharing among parallel power modules?
The UCC39002P uses current-mode control to sense output current in each module and adjust the output voltage slightly so that each parallel supply contributes an equal share. With an input voltage range up to 14.25V and 1 channel of control, it continuously trims the share bus, keeping current imbalance below a few percent across the parallel supply stack.
For a 5V N+1 redundant power shelf, what adjustable threshold setting does the UCC39002P support?
The UCC39002P provides an adjustable share threshold, allowing the designer to set the acceptable current deviation band between modules. In a typical 5V N+1 server shelf, the threshold is tuned via an external resistor network so that each module stays within a few hundred milliamps of the average, keeping individual module power dissipation balanced across the full 14.25V input range.
Is the UCC39002P available in a surface-mount alternative, or only in the 8-PDIP through-hole package?
The UCC39002P is offered in the 8-pin PDIP through-hole format, which is preferred for prototyping and retrofitting legacy power boards. Texas Instruments offers functionally similar load share controllers in SOIC-8 surface-mount packaging for higher-density PCB layouts. Verify availability and lead time for the package variant you need, as PDIP parts may have longer reorder lead times than SMD alternatives.
