Dual Digital Isolators with DC-DC Converter

KEY FEATURES

The Si88xx integrates Silicon Labs' proven digital isolator technology with an on-chip

isolated dc-dc converter that provides regulated output voltages of 3.3 or 5.0 V (or >5 V

with external components) at peak output power levels of up to 5 W. These devices pro-

vide up to two digital channels. The dc-dc converter has user-adjustable frequency for

minimizing emissions, a soft-start function for safety, a shutdown option and loop com-

pensation. The device requires only minimal passive components and a miniature trans-

former.

• High-speed isolators with integrated dc-dc

converter

• Fully-integrated secondary sensing

feedback-controlled converter with

dithering for low EMI

• dc-dc converter peak efficiency of 83%

with external power switch

The ultra-low-power digital isolation channels offer substantial data rate, propagation de-

lay, size and reliability advantages over legacy isolation technologies. Data rates up to

100 Mbps max are supported, and all devices achieve propagation delays of only 23 ns

max. Ordering options include a choice of dc-dc converter features, isolation channel

configurations and a fail-safe mode. All products are certified by UL, CSA, VDE, and

CQC.

• Up to 5 W isolated power with external

power switch

• Options include dc-dc shutdown, frequency

control, and soft start

• Standard Voltage Conversion

• 3/5 V to isolated 3/5 V

• 24 V to isolated 3/5 V

• 3/5 V to isolated 24 V

• 24 V to isolated 24 V

Applications:

• Precise timing on digital isolators

• 0 – 100 Mbps

• Industrial automation systems

• Hybrid electric and electric vehicles

• Isolated power supplies

low emissions

• RoHS compliant packages

• SOIC-20 wide body

Safety Approval (Pending):

• SOIC-16 wide body

• UL 1577 recognized

• VDE certification conformity

• VDE0884-10

• Isolation of up to 5000 Vrms

• Up to 5000 Vrms for 1 minute

• CSA component notice 5A approval

• IEC 60950

• High transient immunity of 100 kV/µs

(typical)

• CQC certification approval

• GB4943.1

• AEC-Q100 qualified

• Wide temp range

• –40 to +125 °C
