Product Overview
The UCC28700DBVT is a flyback Power Supply Controller provides constant-voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler. It process information from the primary power switch and an auxiliary flyback winding for precise control of output voltage and current. Low start-up current, dynamically controlled operating states and a tailored modulation profile support very low standby power without sacrificing start-up time or output transient response. Control algorithms in the UCC28700 family allow operating efficiencies to meet or exceed applicable standards. The output drive interfaces to a MOSFET power switch. Discontinuous conduction mode (DCM) with valley switching reduces switching losses. Modulation of switching frequency and primary current peak amplitude (FM and AM) keeps the conversion efficiency high across the entire load and line ranges.
- <lt/>30mW No-load power for 5-star rating
- Primary-side regulation (PSR) eliminates opto-coupler
- ±5% Voltage and current regulation
- Density charger designs
- Quasi-resonant valley-switching operation for highest overall efficiency
- Patent-pending frequency-jitter scheme to ease EMI Compliance
- Clamped gate-drive output for MOSFET
- Overvoltage, low-line and overcurrent protection
- Green product and no Sb/Br
