2.4.2

Electrical Characteristics of PWM Section

Unless otherwise specified under conditions, the minimum and maximum ratings listed in the following table apply

over the entire specified operating ratings of the PD70211 device. Typical values stated, are determined either by

design or by production testing at 25 °C ambient. Voltages are with respect to IC ground (VPN_IN).
