Description
The UCC28730-Q1 isolated-flyback power supply controller provides constant-voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler. A minimum switching frequency of 30 Hz achieves less than 5 mW of no-load power.
This device processes information from the primary power switch and an auxiliary flyback winding for precise control of output voltage and current.
An internal 700-V start-up switch, dynamically- controlled operating states and a tailored modulation profile support ultra-low stand-by power without sacrificing start-up time or output transient response. Control algorithms in the UCC28730-Q1 allow operating efficiencies to meet or exceed applicable standards. Discontinuous conduction mode (DCM) operation with valley-switching reduces switching losses. Modulation of the switching frequency and primary current peak amplitude (FM and AM) keeps the conversion efficiency high across the entire load and line ranges.
