- 6.5 V/8 V/10 V boost controller
- 5 V linear voltage reg. (100 mA)
- CAN FD up to 5 Mbit/s
- Up to 4 LIN transceivers
- Diagnosis and supervision functions
- Low-Power & Fail-Safe operating mode
- Full wake capability
- SW compatibility w/in SBC family
SMPS voltage regulator with 5 V or 3.3 V output voltage
The devices include failsafe features to support ECU functional safety concepts, wake inputs to monitor trigger signals, and very low quiescent current in low power modes with full wake-up capability. All devices feature an exposed pad VQFN-48 (7 x 7 mm) power package. The entire family is software compatible (also with other Infineon SBC products) and pin-to-pin within the DC/DC SBC family.
Highly-efficient DC/DC technology
- Space saving: 80 percent PCB board space savings by integrating eight chips in one single VQFN package with a 7 x 7 mm footprint.
- Energy saving: SMPS at greater than 80 percent efficiency excels in system power savings. Minimal quiescent current and intelligent power-saving modes including stop and sleep mode complement the system solution.
- High-system reliability: Comprehensive diagnostics, supervision, and fail-safe features.
- Reduced cost: Minimum number of external components reduce. Savings in BOM cost, part placing and handling, PCB board size, purchasing, and development.
- Multiple and flexible designs: Compatible hardware and software reduce design costs and effort, enabling usage in various applications.
DC/DC SCB family is pin-to-pin and software compatible
The entire family is pin-to-pin and software compatible. The DC/DC SBC family allows scalability from two up to four LIN transceivers. The main supply voltage is either 5 V or 3.3 V, depending on the variant. It is also software compatible with the Lite, Mid-Range+, and Multi-CAN Power+ SBC families (TLE94x1, TLE926x and TLE9278).
What are the key benefits of the DC/DC SBC Family?
High-efficiency SMPS buck and boost to supply high current even at low battery voltage; Low-drop voltage regulator for on- and off-board supply; Flexible number of integrated LIN transceivers; Very low quiescent current; Very small leadless package supporting Automated Optical Inspection (AOI); Pin compatibility among all family members; Wide supply input voltage and temperature range; Reduced system cost through low component count and less PCB space; Excellent EMC and ESD performance meeting major car OEM requirements
