Notes
1. The start-up supply current is specified in a temperature (Tvj) range of 0 to 125 °C. For Tvj <0 and Tvj >125 °C the
start-up supply current is <350 µA.
2. The clamp margin is defined as the voltage difference between turn-on of the clamp and start of oscillation. The
clamp is in the off-state at start of oscillation.
3. Data sampling of VRS(ctrl) is performed at the end of conduction of T2.
4. The total supply current is specified in a temperature (Tvj) range of 20 to +125 °C. For Tvj < 20 and Tvj >125 °C the
total supply current is <1.5 mA.
5. Data sampling of VRS(cap) is performed at the start of conduction of T2.
6. Within the allowed range of RRREF, defined as 30 k+10%.
7. Typical values for the on and off resistances at Tvj = 87.5 °C are: RG2(on) and RG1(on) = 164 , RG2(off) and
RG1(off) = 100 .
8. The input current at pin RHV may increase to 1600 µA during voltage transient at Vin. Only for currents IRHV beyond
approximately 550 µA is the oscillator frequency proportional to IRHV.
9. The symmetry SYMff is calculated from the quotient SYMff = T1tot/T2tot, with T1tot the time between turn-off of G2 and
turn-off of G1, and T2tot the time between turn-off of G1 and turn-off of G2.
