UG-734 ADP1046A Evaluation Board User Guide TOPOLOGY AND CIRCUIT DESCRIPTION This evaluation board circuit consists of the ADP1046A in a voltage of 1 V, which is differentially sensed. Output current is typical isolated dc-to-dc switching power supply in a full bridge measured using a sense resistor (R2), which is also differentially phase shifted topology with synchronous rectification. The circuit sensed. To protect the synchronous rectifiers from exceeding provides a rated output load of 48 V/12.5 A from a nominal the peak reverse voltage, an RCD clamp is implemented (D58, input voltage of 385 V dc operated in continuous conduction D59, R112 to R115, and C94). mode (CCM) at all times. The ADP1046A provides functions The primary current is sensed through the CS1 pin with a small such as output voltage regulation, output overvoltage protection, RC time constant (R44 and C22) that acts as a low-pass filter to input and output current protection, primary cycle by cycle remove the high frequency noise on the signal. An additional protection, and overtemperature protection. Figure 70 provides RC can be placed; however, the internal Σ-Δ analog-to-digital a top level schematic that describes the power flow and auxiliary converter (ADC) naturally averages the signal. The position of power supply that starts up at 50 V dc and provides power to the current transformer is placed in series with the resonant the ADP1046A through a 3.3 V low dropout regulator (LDO), inductor to avoid saturation. the iCoupler® isolation plus gate drivers, the on-board fan, and Line voltage feedforward is implemented using an RCD circuit the synchronous rectifier drivers. The auxiliary power supply (D13, R59, R64, C38, and C43) that detects the peak voltage at using the transformer (T3) and IC (U10) generates a 12 V rail the synchronous field effect transistor (FET). There are two on the primary side and a 13 V rail on the secondary side. The time constants that can be implemented in series with each main power transformer (T12) provides a wide input voltage other. The time constants must be matched such that it retains range (340 V dc to 410 V dc), and the circuit has a wide zero the peak value during the switching frequency period, but also voltage switching (ZVS) range down to 10% of the rated load. is not too long in case there is a step down change in the input The primary side consists of the input terminals (JP8 and JP9), voltage. This peak voltage is further ratioed and fed in the the switches (Q1 to Q4), the current sense transformer (T5), ACSNS pin of the controller (ADP1046A). A thermistor (RT1) and the main transformer (T1). There is also a resonant inductor is placed on the secondary side close to the synchronous FET that aids in zero voltage switching at lighter load conditions. and acts as thermal protection for the power supply.

ESD Caution ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality. Legal Terms and Conditions By using the evaluation board discussed herein (together with any tools, components documentation or support materials, the “Evaluation Board”), you are agreeing to be bound by the terms and conditions set forth below (“Agreement”) unless you have purchased the Evaluation Board, in which case the Analog Devices Standard Terms and Conditions of Sale shall govern. Do not use the Evaluation Board until you have read and agreed to the Agreement. Your use of the Evaluation Board shall signify your acceptance of the Agreement. This Agreement is made by and between you (“Customer”) and Analog Devices, Inc. (“ADI”), with its principal place of business at One Technology Way, Norwood, MA 02062, USA.
