Not Recommended for New Designs
Not recommended for new designs.
Features
- Single controller performs synchronous rectification and post regulation
- Independent regulation of multiple outputs from a common secondary winding
- Turn-on shoot-through inherently eliminated
- Primary switch turns ON and OFF with zero current
- No synchronizing or any other signals needed across the isolation boundary
- Eliminates the need for a secondary bias supply
- Independent soft start, ON/OFF, remote sense and current limit for each output
- Resistive or inductive current sensing with 2 V current signal and 2.5 V reference for external applications
- 4.5 V to 18 V operation
- Max. operating frequency to 1 MHz
- Low-profile 16-pin TSSOP package
- Based on Semtech’s patent-pending Combi-Sync™ concept
- Telecom isolated DC-to-DC converters with multiple low-voltage outputs
- High-density brick and sub-brick modules with independently regulated multiple outputs
- Distributed power architectures
- Isolated VRMs
