SC1139DG Description
SC1139DG Energy-Efficient, Accurate CV Switcher With CC Control for Adapters and Chargers Product Highlights Dramatically Simplifies CV Converters Eliminates optocoupler and all secondary CV/CC control circuitry Eliminates all control loop pensation circuitry Enables Clampless™ designs Advanced Performance.
SC1139DG Key Features
- pensates for cable voltage drop
- pensates for external ponent temperature variations
- Very tight IC parameter tolerances using proprietary trimming
- Frequency jittering greatly reduces EMI filter cost
- Operation frequency of 105 kHz to minimize transformer size
- Minimum operation frequency of 1.4 kHz improved transient
- Auto-restart protection reduces power delivered by about 85%
- Hysteretic thermal shutdown
- automatic recovery reduces power supply returns from the field
