application notes vin - these pins provide the input power connection to the msk5502. all vin pins must be connected for proper opera- tion. gnd - these pins provide the vin and vout ground refer- ence. all gnd pins must be connected for proper operation. vout - these are the output pins for the device. all vout pins must be connected for proper operation. enable - when tied low, the msk5502 is enabled and oper- ates normally. when tied high, the msk5502 is disabled and vout is connected to ground. 3 pin functions input and output bypassing the msk5502 has an internal ceramic output capacitor, which in most cases, is sufficient to stabilize the internal control loop. additional capacitance between 1 and 10uf can be added. the output capacitor requires an esr from 0.01 to 1 . higher capacitor values improve load transient response. proper input bypassing is required in order to filter out noise and provide low ac impedance source. the msk5502 has an internal ceramic input capacitor connected between vin and gnd. in most applications the internal ca- pacitor is sufficient for proper operation. additional input capacitance up to 1uf can be added to maximize transient response and minimize power supply transients. thermal limiting the msk5502 has an internal thermal shutdown feature. the typical junction temperature threshold is 275c with 10c of hysteresis. when in thermal shutdown, the pass transistor is disabled and vout is internally connected to ground. overcurrent protection the msk5502 has an internal current limiter feature. the typical current limit threshold is 200ma. in the case of short, the msk5502 may switch between current limit and ther- mal shutdown mode. enable function when the enable pin is tied low the msk5502 is enabled and operates normally. when the enable pin is tied high the msk5502 is disabled and vout is internally connected to ground. the disable feature acts the same as the thermal shutdown feature. preliminary rev. - 5/14
