Application Information

Hiccup Mode Short Circuit Control

When the converter output is shorted or the device is overloaded,each high-side MOSFET current- limit event turns off the high-side MOSFET and

turns on the low-side MOSFET. An internal counter is used to count the each current-limit event. The counter is reset after consecutive high-side

MOSFETs turn on without reaching current limit. If the current- limit condition persists, the counter fills up. The control logic then stops both high-

side and lowside MOSFETs and waits for a hiccup period, before attemping a new soft-start sequence. The counter bit is decided by V

FB

voltage.

If V

FB

≤ 0 2, the counter is 3-bit counter; if V

FB

>0.2 the counter is 6-bit counter. The typical hicuup made duty cycle is 1.7%. The hicuup mode is

disable during soft-start time.

Thermal Shutdown

When the die temperature exceeds +150°C, a reset occurs and the reset remains until the temperature decrease to +120°C, at which time the

circuit can be restarted.
