NXP Semiconductors TEA1721ADB1060,598

Overview

TEA1721ADB1060,598 from NXP Semiconductors is a non-isolated AC/DC buck and buck/boost converter demonstration board based on the TEA1721XT controller IC. It delivers +12 V or −12 V DC output at up to 200 mA (2.5 W), operates from universal mains input (85–265 V AC), features built-in overcurrent and short-circuit protection, and achieves ≤8 mW no-load power consumption at 230 V AC - meeting Energy Star 2.0 Level V requirements by >10× margin.

For engineers reviewing the TEA1721ADB1060,598 datasheet, TEA1721ADB1060,598 pinout, TEA1721ADB1060,598 application, or TEA1721ADB1060,598 equivalent, this evaluation board supports rapid validation of non-isolated SMPS designs for white goods, industrial controls, and low-power auxiliary supplies where triac-driven third-quadrant switching or surge-prone environments demand robust, ultra-low-standby operation.

Technical Context

The TEA1721ADB1060,598 implements two distinct topologies via jumper configuration: buck mode delivers +12 V DC referenced to neutral/phase, while buck/boost mode generates −12 V DC relative to neutral/phase - enabling direct drive of triacs in white goods applications. It uses an integrated TEA1721XT controller with internal MOSFET, operating at ~50 kHz switching frequency.

EMI filtering meets EN 55022 Class B with ≥10 dB margin; optional TVS diodes (BZG03-C200) clamp input surges to ≤400 V DC; output voltage accuracy is +2 % to −5 %, with stability ≥±1 % across 10–100 % load range. No-load power is 5 mW (115 V AC) or 8 mW (230 V AC).

FAQ

What is the primary function of the TEA1721ADB1060,598?

The TEA1721ADB1060,598 is a demonstration board that implements a non-isolated AC/DC buck or buck/boost converter using the TEA1721XT controller. Its primary function is to provide +12 V or −12 V DC output from universal mains input for evaluation and reference design purposes - not as a standalone production module. The TEA1721ADB1060,598 enables rapid validation of triac gate drive and ultra-low-standby auxiliary power architectures.

How do I configure the TEA1721ADB1060,598 for buck versus buck/boost operation?

The TEA1721ADB1060,598 uses two zero-ohm jumpers: JP2 must be installed for buck mode (+12 V output), while JP1 must be installed for buck/boost mode (−12 V output). Both jumpers must not be installed simultaneously. Configuration is hardware-selectable only - no firmware or external programming is involved. The TEA1721ADB1060,598 schematic and layout are optimized for each topology per NXP UM10522 Rev. 1.1.

Does the TEA1721ADB1060,598 include surge protection?

Yes - the TEA1721ADB1060,598 includes optional bidirectional TVS diodes (D2 and D3, BZG03-C200) across the DC bus to limit surge voltage to ≤400 V DC. This feature is implemented per NXP's implementation guidelines and provides protection against line transients common in industrial and appliance environments. The TEA1721ADB1060,598 documentation states surge protection is optional and can be omitted if not required.

What is the no-load power consumption of the TEA1721ADB1060,598?

The TEA1721ADB1060,598 achieves ≤8 mW no-load power consumption at 230 V AC / 50 Hz, and ≤5 mW at 115 V AC / 60 Hz - verified in NXP UM10522 Table 2. This performance exceeds Energy Star 2.0 Level V requirements (300 mW) by more than two orders of magnitude. The TEA1721ADB1060,598 leverages the TEA1721XT's ultra-low standby architecture to minimize idle losses.

Is the TEA1721ADB1060,598 certified for EMC compliance?

The TEA1721ADB1060,598 has been tested and confirmed to meet EN 55022 Class B radiated and conducted emissions limits, with a measured margin of at least 10 dB against formal limits - as documented in Section 6.1 of NXP UM10522. However, the TEA1721ADB1060,598 is an evaluation board; final system-level EMC certification remains the responsibility of the end-equipment designer.
