Figure 2. MAX1536 Functional Diagram
extended off-time to control the current. Operation dur-
ing a short-circuit or overload is similar to forced-PWM
mode except the off-time is 4 × t OFF . At the end of each
off-time, the PMOS switch turns on and remains on until
the output is in regulation or the current through the
switch increases to the 4.8A current limit. When the
PMOS switch turns off, it remains off for four times the
programmed off-time (t OFF ), and the NMOS synchro-
nous switch turns on. Since either the NMOS or the
PMOS switch is always on, the inductor current is con-
tinuous. The RMS inductor current during a short circuit
remains below the 4.8A current-limit threshold. The
MAX1536 operates using the extended off-time until the
short-circuit or overload is removed and V FB > 0.3 ×
V REFIN . Prolonged short circuit or overload can result in
thermal shutdown.
