Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL78219ARTZ

ISL78219ARTZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78219ARTZ is an obsolete automotive boost regulator featuring a 4.0A integrated low-side MOSFET with 120mΩ on-resistance. 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 and 1.22MHz for optimized transient response and component size. It achieves over 90% efficiency, reaching 93% at 5V in/12V out (0.5A). Packaged in a 10-lead TDFN with a maximum height of 0.8mm, it includes adjustable soft-start and internal thermal protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated 4.0A low-side MOSFET with low on-resistance for high current delivery
Selectable switching frequencies enable smaller external components and faster transient response
External compensation pin allows flexibility with low ESR ceramic output capacitors
Ultra-low shutdown current under 1μA supports extended battery life

Voltage Regulators - DC DC Switching Regulators Applications

Automotive boost regulation systems
Battery-powered electronic devices requiring step-up conversion
Applications utilizing AEC-Q100 Grade 2 qualified components

Voltage Regulators - DC DC Switching Regulators Procurement Notes

The ISL78219ARTZ is officially classified as obsolete by Renesas Electronics Corporation. Current availability is listed as out of stock, and samples are not available through standard channels. Designers must verify end-of-life status and consider alternative solutions for new production designs. Existing inventory should be managed carefully due to the discontinued manufacturing status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

This component is suitable for applications requiring a compact, high-efficiency boost converter with a wide input voltage range starting as low as 2.3V. The integrated power switch reduces external component count and PCB footprint. Selection should account for the specific switching frequency requirements regarding inductor size versus transient performance. External compensation network design is necessary to optimize stability with chosen output capacitors.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL78219ARTZ belongs to the ISL78219 family of high-frequency, non-synchronous step-up voltage regulators. It utilizes current-mode control with constant PWM switching. The ARTZ suffix indicates a tube carrier type for the 10-lead TDFN package. This part is designed for automotive environments, meeting AEC-Q100 Grade 2 standards for temperature ranges between -40°C and +105°C.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

As the ISL78219ARTZ is obsolete, no direct public substitute part numbers are confirmed in the provided documentation. Designers should consult Renesas for current portfolio recommendations or evaluate other automotive-grade boost regulators with similar electrical specifications and package constraints.
