NOTE:
*1: "Supply Current 1" is the value when the IC is constantly switching. In actual operation, the oscillator periodically switches, resulting in lower
power consumption.
*2: EXT H ON resistance can be calculated by (0.4 x Rp) / (V
EXT
- Vpull). * Change Vpull so that V
EXT
will become V
OUT

*3: EXT L ON resistance can be calculated by (V
