The TNY277PN from Power Integrations is part of the TinySwitch-III family, designed for energy-efficient off-line switching applications. This component offers enhanced flexibility and an extended power range, making it suitable for chargers and adapters for various portable devices.
Key electrical specifications include an output power capability of 13W for a 230 VAC adapter and 23.5W peak or open frame. The current limit is selectable via a BP/M capacitor value, allowing optimization for efficiency or peak power. It features simple ON/OFF control with no loop compensation required and is self-biased, eliminating the need for a bias winding.
Enhanced safety and reliability features include accurate hysteretic thermal shutdown protection with automatic recovery and improved auto-restart for fault conditions. Frequency jittering is employed to reduce EMI filter costs. The device is available in DIP-8C and SMD-8C packages, with mounting options including through-hole.
This switcher easily meets global energy efficiency regulations, with no-load power consumption below 150 mW at 265 VAC without a bias winding. Its design considerations include pin-out simplification for heatsinking and electrically quiet SOURCE pins for low EMI.
