产品概览
The TEA19161T is an NXP GreenChip™ digital controller for high-efficiency resonant (LLC) power supplies. Designed to pair with the TEA19162T PFC controller, it introduces a low-power mode between continuous switching and burst mode for high efficiency at all load levels. The device operates up to 500kHz half-bridge switching frequency and achieves system no-load power below 75mW.
