• Description: 6a Digital-dc Synchronous Step-down Dc-dc Converter
• Manufacturer: Intersil Corporation

Resistor Settings: This method allows a greater range
of adjustability when connecting a finite value resistor
(in a specified range) between the multi-mode pin and
SGND.
Standard 1% resistor values are used, and only every
fourth E96 resistor value is used so the device can
reliably recognize the value of resistance connected to
the pin while eliminating the error associated with the
resistor accuracy. Up to 31 unique selections are
available using a single resistor.
I
configured via the I
PMBus commands. Additionally, any value that has
been configured using the pin-strap or resistor setting
methods can also be re-configured and/or verified via
the I
details.
The SMBus device address and VOUT_MAX are the
only parameters that must be set by external pins. All
other device parameters can be set via the I
The device address is set using the SA pin.
VOUT_MAX is determined as 10% greater than the
voltage set by the VSET pin.
Resistor pin-straps are recommended to be used for all
available device parameters to allow a safe initial
power-up before configuration is stored via the
I
pin-strapping the undervoltage lockout threshold (using
SS pin) to a value greater than the expected input
voltage, thus preventing the device from enabling prior
to loading a configuration file.
