Product details
Overview
TEA8918BAT/2Y from NXP Semiconductors is a digital resonant power controller integrating PFC and LLC control in a single SO-16 package, supporting 160W dual-output (12V/5A & 100V/0.9A) AC-DC conversion with cycle-by-cycle Vcap control, 91.4% peak efficiency at 230Vac/75% load, and <94mW no-load standby power for high-efficiency SMPS designs.
For engineers reviewing the TEA8918BAT/2Y datasheet, TEA8918BAT/2Y pinout, TEA8918BAT/2Y application, or TEA8918BAT/2Y equivalent, this page delivers verified technical context, MTP-programmable protection thresholds (OVP/OCP/OPP), burst-mode ripple control (268mV p-p), dynamic load response (823mV @12V), and LLC mode-switching frequency behavior (98–151kHz) critical for industrial and consumer power supply validation.
Technical Context
The TEA8918BAT/2Y implements digital state-machine-based control for both PFC and LLC stages, enabling precise Vcap regulation with cycle-level accuracy to suppress audible noise and improve light-load efficiency. It supports three operating modes-High Power (HP), Low Power (LP), and Burst Mode (BM)-with programmable transition levels (e.g., HP→LP at 30%, LP→BM at 10%) and distinct switching frequencies per mode.
Protections include auto-recovering OCP (12V/18A, 100V/5.04A), OPP (12V/7.28A, 100V/1.735A), and OVP (12V/14V, 100V/104V), all configurable via internal MTP memory. The device eliminates external HV resistors by integrating current sources for SNSAUX and SNSCURPFC sensing, and removes clamping diodes through enhanced pin robustness (SNSCURPFC withstands −18V with >100Ω series resistance).

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TEA88181 | Legacy analog PFC+LLC combo; no MTP programming; requires external HV resistors and clamping diodes | Lacks digital burst-mode optimization and Vcap control; higher audible noise and standby power (>200mW) | Choose only if legacy design reuse or cost-sensitive non-compliant applications require minimal BOM change |
| UCC28070DWR | TI dual-phase CCM PFC + standalone LLC controller; separate ICs; analog control loops; no integrated MTP | Requires additional gate driver, compensation networks, and protection logic; larger footprint and higher component count | Select when system-level flexibility (e.g., independent PFC/LLC tuning) outweighs integration benefits of TEA8918BAT/2Y |

FAQ
What is the maximum output power supported by the TEA8918BAT/2Y in a typical dual-rail design?
The TEA8918BAT/2Y is validated for 160W operation in dual-output configurations (12V/5A and 100V/0.9A) on the NXP 160W demo board. Its digital control architecture maintains stable ZVS and <10% cross-regulation across full load, making TEA8918BAT/2Y suitable for high-power industrial and audio applications where thermal headroom and transient response are critical.
Does the TEA8918BAT/2Y require an external auxiliary supply for startup?
No - the TEA8918BAT/2Y integrates a high-voltage startup circuit and internal 5V regulator (SUPREG pin), enabling direct connection to bulk DC after bridge rectification. This eliminates the need for an auxiliary winding or external bias supply, reducing transformer complexity and lowering no-load power to 94mW at 230Vac, a key advantage over legacy controllers like TEA88181.
How does the TEA8918BAT/2Y achieve low acoustic noise in burst mode?
The TEA8918BAT/2Y uses patented digital Vcap control with cycle-by-cycle accuracy to precisely manage LLC resonant timing during burst mode, preventing chaotic switching that causes audible transformer/choke vibration. Measured acoustic noise is 28.8dB at full load - well below the 30dB limit - confirming TEA8918BAT/2Y's suitability for noise-sensitive audio and medical environments.
What protection features are implemented in hardware versus configured via MTP in the TEA8918BAT/2Y?
Core protections - OVP (12V/14V, 100V/104V), OCP (12V/18A, 100V/5.04A), OPP (12V/7.28A, 100V/1.735A), and brown-in/out - are implemented in hardened analog comparators with fixed thresholds, while their response behavior (safe restart vs. latch, timer durations, and mode-specific activation levels) is stored and adjustable in the TEA8918BAT/2Y's internal MTP memory.
Can the TEA8918BAT/2Y support both 115Vac and 230Vac universal input without hardware changes?
Yes - the TEA8918BAT/2Y automatically adapts to 85–265Vac input via SNSMAINS sensing and dynamically adjusts PFC reference, LLC frequency, and burst-mode entry points. Test data confirms consistent efficiency (91.4% avg at 230Vac, 91.7% at 115Vac), standby power (<94mW), and dynamic response across both ranges, validating TEA8918BAT/2Y for global deployment without manual configuration.
