Description

The TPS40041DRBR is a synchronous Buck DC/DC Controller designed to operate from a 2.25 to 5.5V input source. To reduce the number of external components, several operating parameters are fixed internally; namely, frequency, soft start time and short circuit protection (SCP) levels. One of three short circuit threshold levels may be selected by the addition of an external resistor from the COMP pin to circuit ground. During power on and before the internal soft start commands the output voltage to rise, It enters a calibration cycle, measures the current out of the COMP pin and selects an internal SCP threshold voltage. At the end of the 1.6ms calibration time, the output voltage is allowed to rise for a 4ms soft start. During operation, the selected SCP threshold voltage is compared to the upper MOSFET"s voltage drop during its ON time to determine whether there is an overload condition.
