Product Description

TheTcS4335B is synchronous converters with aninput-voltage range of 6V to 30V.lt has anintegratedlow-side switching FET that eliminates the need foran external diode which reduces component countEfficiency is maximized through the integrated 90mΩ and 65-mΩ MOSFETs, low lo and pulse skippingat light loads. Using the enable pin,the shutdownsupply current is reduced to 6 uA. This step-downbuck)converter provides accurate regulation for avariety of loads with a well regulated voltagereference that is 1.5% overtemperature.Cycle-by-cycle current limiting on the high-sideMOSFET protects theTCs4335Bin overload situationsand is enhanced by a lowside sourcing current limitwhich prevents current runaway. A low-side sinkingcurrent-limit turns off the low-side MOSFET tOprevent excessive reverse current.Hiccup protection is triggered if the overcurentcondition continues for longer than the preset time.Thermal shutdown disables the device when the dietemperature exceeds the threshold and enables thedevice again after the built-in thermal hiccup time.
