ISL68201 Datasheet, PDF (11/32 Pages) Intersil Corporation – Single-Phase R4 Digital Hybrid PWM Controller

ISL68201
Tables 3 to 6 show the R_UP and R_DW values of each pin for a
specific system design with some tie-high and tie-low options,
which are for easy programming with reduced resistors and can
be used to validate the regulator operation during In-circuit Test
(ICT) for 0V boot-up voltage option. Additional options are
available Intersil’s PowerNavigator™ GUI or Resistor Reader
calculator, please contact Intersil Application support at
www.intersil.com/en/support. DATA for corresponding registers
can be read out via series bus command (DC to DF). Note that
more options are in PowerNavigator™ GUI or Resistor Reader
calculator and the case of 10kΩ tie-high or tie-low is equivalent
0Ω tie-high or tie-low.
