Test Setup Adjust VIN power supply, PVCC bias supply, and external EN supply to 0 V; connect as shown in Figure 3 (non-SV part) or Figure 4 (SV part). Connect VIN supply to PVIN (J1) and GND (J2). For non-SV parts, connect VBIAS supply to PVCC (J20) and PGND (J29). Connect the external enable source to EN (J14) and AGND (J25). Ext. Enable ( 0- 5 VDC ) VBIAS =PVCC ( 0 -5 VDC ) Ext.

Configuration Changes 7.1. Enable Selection The FAN23XX evaluation board can be enabled using an external-enable-logic signal, as shown in Figure 3 and Figure 4. By default, R8 is populated with 1 MΩ to hold EN LOW. For non-SV parts, an auto-enable function can be implemented by placing a shorting jumper in location J6 to enable the part when PVCC is applied. 7.2. PGOOD Jumper J4 is normally populated with a shorting jumper to allow the PGOOD pin to pull HIGH to VCC. For efficiency measurements under extremely light loads, the shorting jumper should be removed for accurate efficiency measurements. 7.3. On-Board Transient Generator Transient generator circuitry, shown in Figure 2, is included on the bottom of the board to facilitate testing of extremely fast transient loads, with the following usage guidelines: A shorting jumper installed on J3 enables the transient generator. Open J3 to conduct efficiency testing. R13 and R14 adjust the frequency and duty cycle of the LM555 timer. J5 can be used to monitor transient frequency and to trigger an oscilloscope. Switch S1 enables turn-on of load switch Q1 or Q2 or both simultaneously. Load applied with Q1 is equal to VOUT/R15; with Q2 equal to VOUT/R16. Use a low duty cycle to minimize power dissipation on PCB. R22/R23 can be increased in value to reduce load current slew rate. © 2013 Fairchild Semiconductor Corporation 8 FEBFAN23XX_LVA • Rev. 1.2 8. Test Procedure 8.1. Measurement Procedure Set up equipment and board as shown in Figure 3 or Figure 4. For efficiency testing, open J3 (disable transient generator) and J4 (open PGOOD). Adjust load to sink 0 A. Monitor VIN on J17(+) and J23(-) as voltage is increased from 0 V to 12 V. Adjust the external enable signal to 3.3 V to enable converter operation. Monitor PVCC on J20(+) and J19(-) as voltage is increased from 0 to 5 V. Monitor VOUT on J24(+) and J23(-). With IOUT from 0 to IOUT,MAX, VOUT should remain in regulation. To disable the converter, adjust the external enable signal to 0 V. After the converter is disabled, reduce PVcc to 0 V; then reduce VIN to 0 V. Table 4.

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. EXPORT COMPLIANCE STATEMENT These commodities, technology, or software were exported from the United States in accordance with the Export Administration Regulations for the ultimate destination listed on the commercial invoice. Diversion contrary to U.S. law is prohibited. U.S. origin products and products made with U.S. origin technology are subject to U.S Re-export laws. In the event of re-export, the user will be responsible to ensure the appropriate U.S. export regulations are followed. © 2013 Fairchild Semiconductor Corporation 18 FEBFAN23XX_LVA • Rev. 1.2
