64 / 92 page  ZIOL2xxx Datasheet © 2016 Integrated Device Technology, Inc. 64 April 26, 2016 Figure 4.4 shows two layout variants as regards the component placement in the case the DC/DC converter is used in the application circuit. The in this figure shown PCBs are the PCBs of the ZIOL2xxx application kits (ZIOL2xxx LabKit: 2-layer-PCB/ ZIOL2xxx USB-Stick: 4-layer-PCB). The complete PCB documentation of the applications kit is available at IDT upon request and is part of the documentation package of the application kits. Another more optimized PCB layout recommendation for utilizing the on-chip DC/DC-converter shows Figure 3.24 in chapter 3.6.4. An appropriated explanation about the considerations behind this recommendation is give in this chapter as well and illustrated in Figure 3.23. Table 4.1 Recommended External Components Symbol Parameter Min Typ Max Unit Notes R1 R 14 1) 112 2) k Ω Value depends on desired output voltage. R2 R 10 k Ω R3 R -1% 49.9 +1% k Ω Low tolerance range resistor (1% class) R4 R -1% 210 +1% k Ω Low tolerance range resistor (1% class) L1 L 10 50 µH Optimal value depends on application requirements. C1 C 10 50 µF Low ESR recommended C2 C 100 nF Low ESR required C3 C 10 µF Low ESR recommended C4 C 100 nF Low ESR required C5 C 10 µF Low ESR recommended D1 Schottky Diode Recommended: small signal low cap schottky diode, e.g. TMMBAT48 (SGS-THOMSON) or similar device VRRM 40 V IF 0.2 A D2, D3 Schottky Diode Only in device applications Recommended: 10BQ040PBF (Vishay) or similar device VRRM 40 V IF 1.0 3) A D4 – D7 Schottky Diode Recommended: BAT64-04W ( nfineon) or similar device, The BAT64-04W has a SOT323 package with two diodes in series. Thus there only one component for one channel (one dual diode for D4/D5 and one dual diode for D6/D7). VRRM 40 V IF 0.1 A Q1 Optocoupler ACPL-217 (Avago Technologies) 1) R2 = 10k Ω, please refer to minimum output voltage V out in Table 2.3 2) R2 = 10k Ω, please refer to maximum output voltage V out in Table 2.3 3) Two channels in operation, each channel drives max. current 4) IMPORTANT: The ratio R4/R3 shall be 4.2084 +/- 2% |
