Added corresponding Pb-free lead finish note (Note 3)
Added corresponding Package Outline Drawing L36.6x6C to page 30.
In “Voltage Margining” on page 22, changed the last sentence in the 2nd paragraph from "A safety feature prevents the user from
configuring the output voltage to exceed VNOM + 10% under any conditions." to "The ZL2106-01 allows 150% margin limits."
+25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested." to new
standard "Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design."
Removed Note "Limits established by characterization and are not production tested." and all references to it.
Added following statement to disclaimer on page 31: “This product is subject to a license from Power One, Inc. related to digital
power technology as set forth in U.S. Patent No. 7,000,125 and other related patents owned by Power One, Inc. These license
rights do not extend to stand-alone POL regulators unless a royalty is paid to Power One, Inc.”
Text above Equation 13 changed
From: The reference device must be configured to have a minimum Time-On Delay of 10ms greater than the member device as
shown in Equation 13.
To: The reference device must be configured to have a minimum Time-On Delay and Time-On Rise as shown in Equation 13.
Made correction to Equation 13 to read
From: tONDLY(REF) >/- tONRISE(REF) + 5ms
To: tON
Figure 22, last row changed
From: 1.8 5 5 15 5
To:
Revamped Voltage Tracking Section adding details about the tracking feature. Changed in Page 1, 1st paragraph "The ZL2106
is an innovative power conversion..." to "The ZL2106 is a digital power conversion..."
Made correction to Figure 19 - Connected SDA and SCL to Member device.
Made correction to Figure 23 by changing SDA and SCL labels in each device to “EN”. Added word “Enable” and added labels
CFG, SS, R1, R3, R2 and R4.
Changed in Voltage Tracking - Ratiometric on page 23 first sentence changed from:
“This mode configures the ZL2106 to ramp its output voltage at a rate that is a percentage of the voltage applied to the VTRK
pin”. to “This mode configures the ZL2106 to ramp its output voltage as a percentage of the voltage applied to the VTRK pin”.
Titles of Table in Figure 22 changed from “Tracking Configuration Example 1A, 1B, 2A, 2B” to “Tracking Configuration Figure 20
(A), 20 (B), 21 (A), 21 (B)”.
Figures 20and 21 added “0” and “EN” to Timing Tracking Graphics.
