______________________________________________________________________________________
Because this ramp is applied to the current-limit circuit,
the actual time for the output voltage to ramp up
depends on the load current and output capacitor
value. Using Figure 1’s circuit with a 2A load and no
SS capacitor, full output voltage is reached about
600μs after ON_ is driven high.
Boost Capac itors (C4, C5)
Capacitors C4 and C5 store the boost voltage and pro-
vide the supply for the DH3 and DH5 drivers. Use 0.1μF
and place each within 10mm of the BST_ and LX_ pins.
Boost Diodes (D1A, D1B)
Use high-speed signal diodes; e.g., 1N4148 or equivalent.
Table 3. Surface-Mount Components
(See Figure 1 for schematic diagram and Table 4 for phone numbers.)
Bypass Capac itors
Input Filter Capacitors (C1, C13)
Use at least 3μF/W of output power for the input filter
capacitors, C1 and C13. They should have less than
150m
ESR, and should be located no further than
10mm from N1 and N2 to prevent ringing. Connect
the negative terminals directly to PGND. Do not
exceed the surge current ratings of input bypass
capacitors.
VPP and VDD Bypass Capacitors (C10, C11, C12)
Use 2.2μF for VDD, and 1μF for VPPA and VPPB.
