11/16 applications information functional description xr76201 is a synchronous step-down proprietary emulated current-mode constant on-time (cot) regulators. the on- time, which is programmed via r on , is inversely proportional to v in and maintains a nearly constant frequency. the emulated current-mode control is stable with ceramic output capacitors. each switching cycle begins with gh signal turning on the high-side (control) fet for a preprogrammed time. at the end of the on-time, the high-side fet is turned off and the low-side (synchronous) fet is turned on for a preset minimum time (250ns nominal). this parameter is termed minimum off-time. after the minimum off-time, the voltage at the feedback pin fb is compared to an internal voltage ramp at the feedback comparator. when v fb drops below the ramp voltage, the high-side fet is turned on and the cycle repeats. this voltage ramp constitutes an emulated current ramp and makes possible the use of ceramic capacitors, in addition to other capacitor types, for output filtering. enable/mode input (en/mode) en/mode pin accepts a tri-level signal that is used to control turn on/off. it also selects between two modes of operation: forced ccm and dcm/ccm. if en is pulled below 1.8v, the regulator shuts down. a voltage between 2.0v and 2.8v selects the forced ccm mode which will run the regulator in continuous conduction at all times. a voltage higher than 3.1v selects the dcm/ccm mode which will run the regulator in discontinuous conduction at light loads. selecting the forced ccm mode in order to set the regulator to operate in forced ccm, a voltage between 2.0v and 2.8v must be applied to en/mode. this can be achieved with an external control signal that meets the above voltage requirement. where an external control is not available, the en/mode can be derived from v in . if v in is well regulated, use a resistor divider and set the voltage to 2.5v. if v in varies over a wide range, the circuit shown in figure 22 can be used to generate the required voltage. note that at v in of 5.5v and 40v the nominal zever voltage is 4.0v and 5.0v respectively. therefore for v in in the range of 5.5v to 40v, the circuit shown in figure 22 will generate v en required for forced ccm. selecting the dcm/ccm mode in order to set the regulator operation to dcm/ccm, a voltage between 3.1v and 5.5v must be applied to en/mode pin. if an external control signal is available, it can be directly connected to en/mode. in applications where an external control is not available, en/mode input can be derived from v in . if v in is well regulated, use a resistor divider and set the voltage to 4v. if v in varies over a wide range, the circuit shown in figure 23 can be used to generate the required voltage. r1 30.1k, 1% r2 35.7k, 1% v in en/mode zener mmsz4685t1g or equivalent rz 10k figure 22. selecting forced ccm by deriving en/mode from v in v in en/mode zener mmsz4685t1g or equivalent rz 10k v en figure 23. selecting dcm/ccm by deriving en/mode from v in xr 76201 rev1a
