UM10972 TEA1916DB1262 digital resonant 240 W/12 V power supply demo board Rev. 1.1 8 June 2018 User manual COMPANY PUBLIC Document information Information Content Keywords TEA1916DB1262, TEA19161T, TEA19162T TEA1995T 240 W, LLC, resonant, half-bridge, PFC, controller, converter, burst mode, power supply, demo board, high efficiency, 80+ certification Abstract The TEA19161T is a digital LLC controller. It is used in combination with the PFC controller TEA19162T.Combining these two ICs with the SR controller TEA1995T at the secondary side results in a high-efficient resonant converter over the whole output power range. This document describes such a resonant power supply design with a 240 W (12 V/20 A) typical output power. It operates in normal mode for high and medium power levels, in low-power mode at medium and low power levels, and in burst mode at (very) low power levels. Low-power mode and burst mode operation provide a reduction of power losses, resulting in a higher efficiency at lower output power levels. Power levels for switching over from one mode to another mode can be selected by adjusting component values. The efficiency at high power levels is well above 90 %. No-load power consumption is well below 100 mW. At 250 mW output power, the input power is well below the 500 mW (complies easily with EUP lot6).NXP Semiconductors UM10972 TEA1916DB1262 digital resonant 240 W/12 V power supply demo board Table 1.Revision history Rev Date Description v.1.1 20180608 second, updated issue Modifications: Section 7Bill of Material has been updated.
