zl2103 Intersil Corporation, zl2103 Datasheet - Page 8

• Manufacturer Part Number: zl2103
• Description: 3a Digital-dc Synchronous Step-down Dc/dc Converter
• Manufacturer: Intersil Corporation

Electrical Specifications
Boldface limits apply over the operating temperature range, -40°C to +85°C.
NOTES:
10. Refer to Safe Operating Area in Figure 8 and thermal design guidelines in AN2010.
11. Does not include margin limits.
12. Percentage of Full Scale (FS) with temperature compensation applied.
13. The device requires a delay period following an enable signal and prior to ramping its output. Precise timing mode limits this delay period to approx
14. Precise ramp timing mode is only valid when using EN pin to enable the device rather than PMBus enable. Precise ramp timing mode is automatically
15. The devices may require up to a 4ms delay following the assertion of the enable signal (normal mode) or following the
16. Switch node current should not exceed I
17. Factory default is the initial value in firmware. The value can be changed via PMBus commands.
18. Maximum duty cycle is limited by the equation MAX_DUTY(%) = [1 - (150×10
19. t
20. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
