Texas Instruments UCC28730 | Demoboard PMP41063

Beschreibung

This reference design provides an isolated 12-V, 48-W output power conversion with cascaded flyback topology. The power supply can be powered from the 300-V to 1,000-V direct current (DC) input. This design uses valley switching flyback controller UCC28730 to achieve less than 70-mW low standby power consumption at 1,000-V input voltage to extend the battery lifetime.

Eigenschaften

• Wide input-voltage range from 300-V to 1,000-V input voltage
• Less than 70-mW no-load power consumption at 1,000-V input voltage
• Primary-side regulation design (no optocoupler) extend product lifetime
• Minimized output undershoot and overshoot during load transient
• Uniform start-up time across input voltage range
• 86.14% efficiency at 1,000-V input and 48-W output

Typische Anwendungen

• 300V-1000V input 48-W isolated auxiliary power
