Machine Model (Tested per JESD22-A115-A) . . . . . . . . . . 225V

Charged Device Model (Tested per JESD22-C101D) . . . . 2.2kV

page 1 - Changed Related Literature AN1564 title from “ISL9305IRTZEVAL1Z and ISL9305HIRTZEVAL1Z Evaluation

Boards” to “ISL9305 and ISL9305H Evaluation Boards”

page 1 - Changed “the ISL9305 can be ordered in factory pre-set power-up default voltages in increments of 100mV

from 0.9V to 3.6V.” to “the ISL9305 can be ordered in factory pre-set output voltage options from 0.9V to 3.6V in 50mV

step.”

page 1 Features - Changed “at 50mV/Step.....0.9V to 3.3V” to “50mV/Step.......0.9V to 3.6V” under LDO1/LDO2 output

voltage I2C programmability.

page 2 - Change the output capacitor value at VOLDO1 and VOLDO2 from "10µF" to "1µF" in the block diagram.

page 4 - Changed Eval Board part numbers in Ordering Information table from “ISL9305IRTBCNLZEV1Z,

ISL9305IRTBFNCZEV1Z, ISL9305IRTAANLZEV1Z” to “ISL9305IRTAANLZEV1Z, ISL9305IRTBCNLZEV1Z,

ISL9305IRTBFNCZEV1Z, ISL9305IRTWBNLZEV1Z, ISL9305IRTWCLBZEV1Z, ISL9305IRTWCNLZEV1Z,

ISL9305IRTWCNYZEV1Z, ISL9305IRTWLNCZEV1Z”

page 12 - Removed PCN “Note 7” under Table 8. Changed “111 to reserve for system use” to “111 to 28.8mV/µs. Changed

“DCD2” to “DCD1” in line B0 of Table 7.

May 25, 2011

FN7605.1 - Table 8 on page 12 changed 111 description from “to immediate” to “reserved for system use (Note 7).”

Added Note to Table 8, which reads "The IC can be damaged when output is programmed from high to low and the

slew rate register is set to 111."

- Changed ordering information EVAL Board name from ISL9305IRTZEVAL1Z to three separate ones

ISL9305IRTBCNLZEV1Z

ISL9305IRTBFNCZEV1Z

ISL9305IRTAANLZEV1Z

- Corrected Theta JA Thermal Information on page 5 for TQFN from 42 to 40.2

- “Electrical Specifications” on page 5:

Added "Boldface limits apply over the operating temperature range, -40°C to +85°C." to common conditions. Bolded

applicable specs.

- Changed “Compliance to datasheet limits is assured by one or more methods: production test, characterization

and/or design.” note in Electrical Spec Table on page 6 to “Parameters with MIN and/or MAX limits are 100% tested

at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production

tested.” per Product Line decision.

- Changed text under Figure 15, from "VOUT = 1.2V" to "VOUT = 1.8V."
