LT4356MP-1/LT4356MP-2 ELECTRICAL CHARACTERISTICSThe l denotes the specifications which apply over the full operatingtemperature range, otherwise specifications are at TA = 25°C. VCC = 12V unless otherwise noted.SYMBOL PARAMETERCONDITIONSMINTYPMAXUNITS IOUT OUT Pin Input Current VOUT = VCC = 12V l 200 300 µA VOUT = VCC = 12V, VSHDN = 0V l 6 14 mA ΔVOUT OUT Pin High Threshold ΔVOUT = VCC – VOUT; EN from Low to High l 0.25 0.5 0.7 V VSHDN SHDN Pin Threshold VCC = 12V to 48V 0.6 1.4 1.7 V l 0.4 2.1 V VSHDN(FLT) SHDN Pin Float Voltage VCC = 12V to 48V l 0.6 1.2 2.1 V ISHDN SHDN Pin Current VSHDN = 0V l –1 –4 –8 µA tOFF(OC) Overcurrent Turn-Off Delay Time GATE from High to Low, ΔVSNS = 0 → 120mV l 2 4 µs tOFF(OV) Overvoltage Turn-Off Delay Time GATE from High to Low, VFB = 0 → 1.5V l 0.25 1 µs Note 1: Stresses beyond those listed under Absolute Maximum Ratings Note 2: All currents into device pins are positive; all currents out of device may cause permanent damage to the device. Exposure to any Absolute pins are negative. All voltages are referenced to GND unless otherwise Maximum Rating condition for extended periods may affect device specified. reliability and lifetime. Note 3: An internal clamp limits the GATE pin to a minimum of 10V above the OUT pin. Driving this pin to voltages beyond the clamp may damage the device.
