PACKAGE LEAD # LEAD SYMBOL FUNCTION s GATE 2, 2B Non-Overlap Delay GATE2 Turn-on Delay Measure delay from GATE2B going low 20.0 45.0 70.0 ns from GATE2B @1.7V to GATE2 going high @1.7V. GATE2B Turn-on Delay Measure delay from GATE2 going low 20.0 45.0 70.0 ns from GATE2 @1.7V to GATE2B going high @1.7V. s GATE 1, 2, 2B Rise & Fall Times VSS=12V,VCC=VSS-VDON GATE1 Rise Time Measure GATE1 Rise Time from 50.0 80.0 ns 90% to 10%. CLOAD = 150pF. GATE1 Fall Time Measure GATE1 Fall Time from 10% to 90%. CLOAD = 150pF. 30.0 60.0 ns GATE2 Rise Time Measure GATE2 Rise Time from 90% to10%. CLOAD = 50pF. 50.0 80.0 ns GATE2 Fall Time Measure GATE2 Fall Time from 10% to 90%. CLOAD = 50pF. 15.0 30.0 ns GATE2B Rise Time Measure GATE2B Rise Time from 90% to10%. CLOAD = 50pF. 50.0 80.0 ns GATE2B Fall Time Measure GATE2B Fall Time from 10% to 90%. CLOAD = 50pF. 15.0 30.0 ns 1 UVSD Undervoltage shutdown lead. Typically this lead is connected through a resistor divider to the main high voltage (VIN) line. If the voltage on this lead is less than 5V then a fault is initiated such that GATE1, GATE2 and GATE2B go low. 2 OVSD Overvoltage shutdown lead. Typically this lead is connected through a resistor divider to the main high voltage (VIN) line. If the voltage on this lead exceeds 5V then a fault is initiated such that GATE1, GATE2 and GATE2B go low. 3V5REF 5V reference output lead. Capable of 20mA nominal output. If this lead falls to 4.5V, a fault is initiated such that GATE1, GATE2 and GATE2B go low. 4 OAM Auxiliary error amplifier minus input. This lead is compared to 1.2V nominal on the auxiliary error amp plus lead and represents the VSS voltage divided by ten. 5 OAOUT Auxiliary error amplifier output lead. Source current 300µA max. 6 OUVDELAY Output undervoltage timing capacitor lead. If the controlled output voltages of either the main or the auxiliary supply are such that either VFB1 or VFB2 is greater that 4.1V nominal, then capacitor from OUVDELAY to ground will begin charging. If the over voltage duration is such that the OUVDELAY voltage exceeds 5V, then a fault will be initiated such that GATE1, GATE2 and GATE2B will go low. 7ILIM1 Pulse by pulse over current protection lead for the auxiliary PWM. A voltage exceeding 1.2V nominal on ILIM1 will cause GATE1 to go low. A voltage exceeding 1.4V nominal on ILIM1 will cause GATE1 to go low for at least two clock cycles. 8 RAMP1 Current Ramp Input Lead for the Auxiliary PWM. A voltage which is linear with respect to current in the primary side of the auxiliary trans former is usually represented on this lead. A voltage exceeding VFB1 - 0.13 on RAMP1 will cause GATE1 to go low. |
