detailed description (continued)
current protection
Current protection is achieved by sensing the high-side power MOSFET drain-to-source voltage drop during
on-time at VCC_CNTP and LL. An external resistor between Vin and TRIP pin in serial with the internal current
source adjusts the current limit. When the voltage drop during the on-time is high enough, the current
comparator triggers the current protection and the circuit is reset. The reset repeats until the over-current
condition is removed.
COMP
COMP is an internal comparator used for any voltage protection such as the output under-voltage protection
for notebook power applications. If the core voltage is lower than the setpoint, the comparator turns off both
channels to prevent the notebook from damage.
SOFT1, SOFT2
Separate softstart terminals make it possible to set the start-up time of each output for any possibility.
STBY1, STBY2
Both channels can be switched into standby mode separately by grounding the STBY pin. The standby current
is as low as 1
μ
A.
ULVO
When the input voltage goes up to about 4 V, the IC is turned on, ready to function. When the input voltage is
lower than the turn-on value, the IC is turned off. The typical hysteresis is 40 mV.
