MAX1583 Evaluation Kit
Changing the Strobe Pulse Width
The MAX1583 EV kit includes a pulse generator for con-
venience in evaluating the strobe function of the
MAX1583. The strobe pulse width is determined by C4.
To change the pulse width of the strobe, replace C4 with
a capacitor corresponding to the following equation:
C4
=
t_PULSE − 275µs
2.73 ×10⁶
The minimum pulse width of the pulse generator is
1ms. Using a strobe pulse longer than 30ms may
require a larger output reservoir capacitance (C2).
Refer to the Reservoir Capacitance vs. Current Limit
section in the MAX1583 data sheet for details on calcu-
lating the required capacitance.
