1. Description
LinkSwitch-TN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the Table 1. Notes: 1. Typical output current in a non-isolated buck converter. Output power capability depends on respective output voltage. See Key Applications Considerations Section for complete description of assumptions, including fully discontinuous conduction mode(DCM) operation. 2. Mostly discontinuous conduction mode. 3. Continuous conduction mode. 4. Packages: P: DIP-8B, G: SMD-8B. For lead-free package options, see Part Ordering Information. under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency
2. Features
> Supports buck, buck-boost and flyback topologies
> System level thermal overload, output short-circuit and open control loop protection
> Excellent line and load regulation even with typical configuration
> High bandwidth provides fast turn-on with no overshoot
> Current limit operation rejects line ripple
> Universal input voltage range (85 VAC to 265 VAC)
> Built-in current limit and hysteretic thermal protection
> Higher efficiency than passive solutions
> Higher power factor than capacitor-fed solutions
> Entirely manufacturable in SMD
