Most modern day electronics equipment requires DC power to properly operate. In turn, DC-powered electronic equipment could be directly converted from AC sources or through rechargeable batteries charged by chargers or adaptors.

Isolated PSR Flyback Topology

Isolated SSR Flyback Topology

Based on isolated flyback and non-isolated high-voltage buck regulators for a mass volume market, Diodes has developed various high performance and yet cost-effective AC-DC controllers, switchers and related IC chips for both primary side and secondary side regulation to address wide ranges of power applications, including: classical chargers, quick chargers, small home appliances, mid-power set-top boxes and networking.

To facilitate ease of product adoption for customers, Diodes has developed various end-product form-factor platform solutions for popular AC-DC chargers and adapters as reference designs.

The reference design kits include evaluation boards, user guides, document system specification and performance benchmarks for user evaluation and customization.

THE DIODES ADVANTAGE

45W LOW-STANDBY POWER USB PD ADAPTORS: AP3108L + APR346 + PD DECODER

The new USB PD charger standard requires high-efficiency solutions (meets DOE Vi and CoC Tier 2) that are capable of operating over the universal mains input range with standby powers less than 30mW while meeting the full USB-PD protocol.

Modern set-top boxes with internal power supply require high-efficiency solutions (meets DOE Vi and CoC Tier 2) with standby powers less than 75mW with no audible noise across all loads.

These are driving the move to quasi-resonant solutions.
