TEA2356DB1624 140W PFC+AHB Demo Board
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information please contact your sales representative.
The TEA2356DB1624 is a 140 W PFC + AHB demonstration board that allows the output voltage to be configured to 5 V, 9 V, 15 V, 20 V, or 28 V. The design integrates the TEA2356 PFC + AHB controller together with the TEA2392 synchronous rectifier (SR) controller, providing a compact and efficient reference solution for high‑performance power conversion.

Features
Key Features
- Complete functionality of a PFC and AHB controller in a single small-size SO16 package
- Integrated high-voltage start-up
- Integrated drivers and high-voltage level shifter (LS)
- High-side driver directly supplied from the low-side driver output
- Accurate boost-voltage regulation
-
PFC can be configured to operate in:
- DCM/QR
- DCM/QR/CCM (also called multimode operation)
- CCM fixed frequency
- Integrated X-capacitor discharge without of additional external components
- Power good function
- PFC jitter for optimized EMI performance
- AHB jitter for optimized EMI performance
- Excellent power factor (PF) and total harmonic distortion (THD), as the PFC current compensates for the input filter current
- Optimum efficiency point tracking in low-power mode for the AHB
- Adaptive current transfer time to cope with spread and varying resonant capacitor value of the AHB
-
Burst-mode of AHB for optimum low power efficiency
- Burst-mode of AHB includes soft start and soft stop to minimize the audible noise in this mode
- Accurate mode transition levels of the AHB (burst-mode, low-power mode and high-power mode)
- Good stability at low resonant-capacitor values of the AHB
- Several parameters can easily be configured during evaluation with the graphical user interface (GUI)
- Can easily be combined with an external standby supply
- Fast start-up behavior
Green Features
- Valley/zero voltage switching for minimum switching losses
- Very high efficiency from low load to high load
- Compliant with latest energy-saving standards and directives (Energy Star, EuP)
- Excellent no-load input power (< 60 mW at 5 V out for the combination of the TEA2356AT with the TEA2392T or TEA2093T)
Protection features
- Independently configurable levels and timers
- Protections can independently be set to be latched, safe restart, or latched after several attempts to restart
- Supply overvoltage protection
- Supply undervoltage protection (UVP)
- Overload protection (OLP)
- Internal and external overtemperature protection (OTP)
- Accurate PFC and AHB overvoltage protection (OVP)
- Second independent overvoltage protection via DRAINPFC pin
- Overvoltage protection of the resonant capacitor (CRESOVP)
- Overcurrent protection (OCP)
- Inrush current protection (ICP)
- Brownin/brownout protection
- Disable input
- Input to reset all protections
