9 / 22 page Test Circuit and Layout Guidelines Fixed Output Voltage Versions 10134724 Component Values shown are for VIN = 15V, VOUT = 5V, ILOAD = 1A. CIN — 470 µF, 50V, Aluminum Electrolytic Nichicon “PM Series” COUT — 220 µF, 25V Aluminum Electrolytic, Nichicon “PM Series” D1 — 2A, 60V Schottky Rectifier, 21DQ06 (International Rectifier) L1 — 68 µH, See Inductor Selection Procedure Adjustable Output Voltage Versions 10134725 Select R1 to be approximately 1 kΩ, use a 1% resistor for best stability. Component Values shown are for VIN = 20V, VOUT = 10V, ILOAD = 1A. CIN: — 470 µF, 35V, Aluminum Electrolytic Nichicon “PM Series” COUT: — 220 µF, 35V Aluminum Electrolytic, Nichicon “PM Series” D1 — 2A, 60V Schottky Rectifier, 21DQ06 (International Rectifier) L1 — 100 µH, See Inductor Selection Procedure R1 —1 kΩ,1% R2 — 7.15k, 1% CFF — 3.3 nF Typical Values CSS — 0.1 µF CDELAY — 0.1 µF RPULL UP — 4.7k (use 22k if VOUT is ≥ 45V) † Resistive divider is required to aviod exceeding maximum rating of 45V/3mA on/into flag pin. †† Small signal Schottky diode to prevent damage to feedback pin by negative spike when output is shorted (CFF not being able to discharge immediately will drag feedback pin below ground). Required if VIN > 40V FIGURE 1. Standard Test Circuits and Layout Guides www.national.com 8 |
