AN8021L Key Features
- It operates at a control frequency up to 700 kHz, realizing the output rise time of 35 ns and the output fall time of 25
- Pre-start operating current is as small as 70 µA (typical) so that it is possible to use a miniaturized start resistor
- Output block employs totem pole method. The
