Fairchild Semiconductor FSEZ1317 WAMY, WA Battery Charger User Guide
Below you will find brief information for Battery Charger FSEZ1317WAMY, Battery Charger FSEZ1317WA. This document describes a 3.5W power supply using an FSEZ1317WAMY device. This power supply is targeted for mobile phone battery chargers for a 30mW solution with high efficiency. The controller used on the board is Fairchild Semiconductor's FSEZ1317WAMY. This third-generation Primary-Side-Regulation (PSR) PWM controller with integrated MOSFET and improved EMI performance provides several features to enhance the performance of low-power flyback converters. The proprietary TRUECURRENT® technology enables precise Constant Current (CC) regulation and simplified circuit design for battery-charger applications. The result is a lower-cost, smaller, and lighter charger compared to conventional designs or a linear transformer. To minimize standby power consumption (30mW at 265VAC), a proprietary Green Mode provides off-time modulation to linearly decrease PWM frequency under light-load conditions. Green Mode assists the power supply in meeting power conservation requirements.

This user guide supports the evaluation board for the FSEZ1317WA. It should be used in conjunction with the datasheet as well as Fairchild’s application notes and technical support team. Please visit Fairchild’s website at www.fairchildsemi.com
. This kit supercedes the FEBFSEZ1317A_CH310v3. The revised kit incorporates the next generation FSEZ1317WA, which implements a new frequency hopping method.
1. Introduction
This document describes a 3.5W power supply using an FSEZ1317WAMY device. This power supply is targeted for mobile phone battery chargers for a 30mW solution with high efficiency.
The controller used on the board is Fairchild Semiconductor’s FSEZ1317WAMY. This third-generation Primary-Side-Regulation (PSR) PWM controller with integrated
MOSFET and improved EMI performance provides several features to enhance the performance of low-power flyback converters. The proprietary TRUECURRENT® technology enables precise Constant Current (CC) regulation and simplified circuit design for battery-charger applications. The result is a lower-cost, smaller, and lighter charger compared to conventional designs or a linear transformer. To minimize standby power consumption (30mW at 265V
AC
), a proprietary Green Mode provides off-time modulation to linearly decrease PWM frequency under light-load conditions. Green
Mode assists the power supply in meeting power conservation requirements. By using the
FSEZ1317WA, a charger can be implemented with few external components and minimized cost. A typical output CV/CC (Constant Voltage / Constant Current) characteristic envelope is shown in Figure 23 and Figure 24.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized
Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
