CHANGE
Updated on page 13 in UVLO section, last sentence from “...programming resistor R5..., The
value of R4...” to “...programming resistor R4..., The value of R5...”. Replaced Figure 38,
Removed Equation after Figure 38. Reworded last sentence in Enable section from “It is
necessary to keep the voltage on the EN low until Vin is greater than 2.5V” to “It is
recommended that the EN voltage should be kept logic low (less than 400mV), until VIN
reaches 2.5V. Refer to Figure 39 for suggested circuit implementation with VIN slew rate.
Added Figure 39. Added Equations 1 and 2 and referencing text.
Added Revision History and Products information.
Moved Soft-Start section to read after PG section on page 13, changed "R4" to "R5" in last
sentence of UVLO section, added reference of both Figures 38 and 39 in Enable section.
9/10/09:
Page 6; Revised last sentence of EN section from:
"Do not leave this pin floating." TO:"Do not connect directly to VIN or leave this pin floating."
9/2/09:
Page 2: Order Info: Added MSL link to Order Info per new standard
Page 2: Revised Typical Application Diagram
Pages 4-5: Per new Intersil standard: Added "Boldface limits apply over the operating
temperature range, -40°C to +85°C." to common conditions of Electrical Specs table. Bolded
MIN MAX columns where applicable. Moved "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." from common conditions of Electrical Specs
table to note in Min Max columns.
Page 6: Added following sentence to EN pin description:
" Keep the EN voltage low in disabled state until Vin settle or above 2.5V."
Revised "FIGURE 37. SKIP MODE OPERATION WAVEFORMS
Page 14: Added FIGURE 38. EXTERNAL RESISTOR DIVIDER graphic and following sentence to
UVLO section:
"To adjust the voltage level of power on and UVLO, use a resistive divider across EN. The input
voltage programming resistor R5 will depend on on the bottom resistor R4, as referred to in
Figure 38. The value of R4 is typically between 10kohm and 100kohm."
Added equation 1 to UVLO section:
Added following sentence to Enable section:
"It is necessary to keep the voltage of the EN low until Vin is greater than 2.5V."
Added to VIN, VDD and LX in Abs Max Rating (DC) or 7V (20ms). Added Intersil Standards as
follows: Added to Electrical Specs conditions at top over-temp note. Updated POD L16.4x4 to
latest version.
Removed the MIN and MAX value of "Peak Skip Limit " in the EC table at page 4.
Replaced the Trans-Resistance (RT) value "0.18" into "0.17" for MIN and "0.22" into "0.23" for
MAX in the EC table on page 4.
