No load at DRIVE pin (CLOAD = 0), TA = TJ. DIL-8, SOIC-8 (Top View) J, N, or D Packages Note 1: VDD forced to 100mV below VDD Zener Voltage Note 2: gm is defined as ∆ICT ∆VFB for the values of VFB where the error amp is in regulation. The two points used to calculate gm are for ICT at 65% amd 35% of its maximum value. 2 |
