Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL78219ARTZ-T
Voltage Regulators - DC DC Switching Regulators Overview
The ISL78219ARTZ-T is an obsolete automotive boost regulator featuring a 4.0A integrated low-side MOSFET with 120mΩ Rds(on). It operates within a +2.3V to +6.0V input range, delivering outputs from 1.1 times Vin up to 24V. The device supports selectable switching frequencies of 640kHz or 1.22MHz for optimized transient response and component size. It achieves high efficiency, reaching 93% at 5V in and 12V out at 0.5A load. The part is housed in a 10-lead TDFN package with a maximum height of 0.8mm, compliant with AEC-Q100 Grade 2 standards for -40°C to +105°C operation.
Voltage Regulators - DC DC Switching Regulators Feature Summary
- High-frequency current-mode control non-synchronous step-up voltage regulation
- Integrated 4.0A low-side MOSFET with low on-resistance for high efficiency
- Selectable switching frequencies to optimize transient response and passive component size
- External compensation pin enabling flexibility with low ESR ceramic output capacitors
Voltage Regulators - DC DC Switching Regulators Applications
- Automotive boost converter applications requiring AEC-Q100 compliance
- Systems needing high efficiency over wide input voltage ranges
- Designs requiring compact PCB footprint through high-frequency operation
Voltage Regulators - DC DC Switching Regulators Procurement Notes
This specific part number is officially listed as obsolete by the manufacturer. Availability is restricted to remaining stock or secondary market sources, with no new production confirmed. Verify authenticity and lot traceability carefully when sourcing from distributors. Ensure the replacement solution meets all original electrical and thermal requirements before integration into new designs.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component only if legacy design compatibility is required, as it is discontinued. For new designs, consider alternative Renesas boost regulators that offer current production status and updated supply chain security. Evaluate the 4.0A switch limit and 24V maximum output against system load requirements. Confirm that the 10-lead TDFN package fits the mechanical constraints of the target application.
Voltage Regulators - DC DC Switching Regulators Part Context
The ISL78219 belongs to the Intersil (now Renesas) family of high-efficiency synchronous and non-synchronous DC/DC converters. It targets automotive and industrial markets requiring robust power management under varying load conditions. The device integrates protection features including internal thermal shutdown and adjustable soft-start to ensure reliable startup sequences.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
As the ISL78219ARTZ-T is obsolete, direct substitutes are not explicitly listed in public documentation. Engineers should consult Renesas for current equivalent boost regulator recommendations that match the 4A switch current and 2.3V minimum input specifications.
