AN11801 TEA19161 and TEA19162 controller ICs Rev. 2.1 7 April 2021 Application note Document information Information Content Keywords TEA19161, TEA19162, PFC, burst mode operation, low-power mode, cycle- by-cycle control, V control, resonant power converter cap Abstract The TEA19161T and TEA19162T are a set of controller ICs for resonant power supplies that include a PFC. To reach a high efficiency at all power levels, the TEA19161T(LLC) introduces a new operating mode: low-power mode. This mode operates in the power region between continuous switching (now called high-power mode) and burst mode. Most LLC resonant converter controllers regulate the output power by adjusting the operating frequency. The TEA19161T regulates the output power by adjusting the voltage across the primary resonant capacitor for accurate state control and a linear power control. External presets can define operation modes and protections. This feature provides flexibility and ease of design for optimizing controller properties to application-specific requirements.NXP Semiconductors AN11801 TEA19161 and TEA19162 controller ICs Table 1.Revision history Rev Date Description v.2.1 20210407 Updated revision v.2 20190107 second revision v.1 20170505 Initial revision AN11801 All information provided in this document is subject to legal disclaimers.
