NXP active bridge rectifier controller (AC-DC) AC-DC control module NXP
NXP Brand Introduction NXP Spot Check

NXP PWM secondary side controller TEA1999TS synchronous rectifier controller. TEA1999TS is a member of the new generation of synchronous rectifier (SR) controller IC series suitable for switching power supplies, which uses adaptive gate drivers to achieve maximum efficiency under any load.

TEA1999TS is a controller IC specifically designed for synchronous rectification on the secondary side of flyback converters. It integrates a sensing stage and a driver stage to drive the SR MOSFET, which rectifies the output of the secondary transformer winding.

TEA1999TS can generate its own power supply voltage for low output voltage battery charging applications or high side rectification applications.

TEA1999TS is made using silicon on insulator (SOI) technology.

The NXP PWM secondary side controller TEA1999TS synchronous rectifier controller adopts TSOP6 (SOT457).

NXP AC-DC Controller TEA1721AT with Integrated Power Switch The TEA1721 is a small and low cost module Switched Mode Power Supply (SMPS) controller IC for low power applications (up to 5 W) and operates directly from the rectified universal mains input. The device includes a high voltage power switch (700 V) and has been optimized for flyback converter topologies to provide high-efficiency over the entire load range with ultra-low power consumption in the no-load condition. It provides a circuit for start-up directly from the rectified mains voltage without any external bleeder circuits. The Burst mode frequency of 905 Hz enables no-load power consumption below < 20 mW at high mains input.
NXP AC-DC Controller TEA1723FT with Integrated Power Switch The NXP AC-DC controller TEA1723 with integrated power switch is a small-sized and low-cost switch mode power supply (SMPS) controller IC, suitable for low-power applications (up to 11 W), and can work directly with rectified mains power. This device integrates a high voltage power switch (700 V) and is optimized for flyback converter topology, which can improve efficiency over the full load range with extremely low no-load power consumption. The device is equipped with a built-in startup circuit, which can be directly started using rectified mains voltage without the need for any external discharge circuit. A hiccup frequency of 1750 Hz can achieve no-load power consumption below 53 mW under high mains input conditions.
Introduction to TEA170 NXP Power Management Chip (Active Bridge Correct AC-DC) Recommended NXP active bridge rectifier controller: TEA1708 is an IC suitable for automatic discharge of X capacitors, with low power consumption characteristics (typical value of 1 mW at 230 V (AC)). Internally integrated with a 500 V clamp circuit, it can protect the IC during power surges. In typical applications with only two 200k Ω resistors, the maximum allowable differential mode surge voltage exceeds 6 kV. No metal oxide varistors are needed to protect the IC. The discharge current of the X capacitor is internally limited to 2.3 mA. Use low-voltage capacitors to set a discharge delay timer externally. Extremely low power consumption combined with high discharge current, large capacity X capacitors can be used to reduce EMI while maintaining low standby power consumption.

GreenChip SMPS Primary Side Control IC with QR/DCM Operation and Active x-Capacitor Discharge The TEA19363LT is a member of the GreenChip family of controller ICs for switched mode power supplies. It is intended for flyback topologies to be used either standalone or together with USB PD or smart charging controllers (like the TEA190x series) at the secondary side. The built-in green functions provide high efficiency at all power levels. The TEA19363LT is compatible with multiple output voltage applications with a wide output range from 5 V to 20 V in Constant Voltage (CV) mode. When used with a secondary-side controller IC, like the TEA190x series, it supports Constant Current (CC) mode down to 3 V output voltage.
