Overview
The CS5173GDR8 is a switching voltage regulator manufactured by onsemi, designed as a high-efficiency boost converter. It delivers a continuous output current of 1.5 A with an adjustable output voltage range from 1.28 V to 40 V. The device operates within an input voltage window of 2.7 V to 30 V and supports selectable switching frequencies of 280 kHz or 560 kHz. Packaged in an 8-SOIC surface-mount format, it is rated for junction temperatures up to 125°C.
Feature Summary
- Integrated synchronous rectification for improved conversion efficiency
- Selectable internal switching frequency options to optimize component size and performance
- Adjustable output voltage capability via external resistor network
Applications
- Battery-powered portable electronics requiring step-up voltage regulation
- General-purpose DC-DC power supply stages in consumer devices
- Industrial control systems utilizing boost topology for voltage elevation
Procurement Notes
Verify the specific ordering suffix and tape/reel configuration against the official datasheet before procurement. Confirm that the selected variant matches the required switching frequency setting and package tolerance. Ensure compliance with RoHS directives if applicable to the target assembly process. Check for any recent lifecycle status updates regarding obsolescence or replacement recommendations.
Selection Notes
Select this component when a compact boost solution is needed for inputs between 2.7 V and 30 V. Consider the 1.5 A current limit and 280/560 kHz frequency options for EMI and inductor sizing trade-offs. Evaluate thermal dissipation requirements for the SOIC-8 package under maximum load conditions. Compare against NCP5173 for higher frequency applications if system constraints demand smaller passive components.
Part Context
This part belongs to the CS5173 family of 1.5 A boost regulators from onsemi. It shares architectural similarities with the CS5171 buck regulator but utilizes a step-up topology. The series is designed for cost-sensitive applications requiring reliable voltage boosting without external synchronization complexity. It complements other PMIC offerings in the portfolio for complete power management solutions.
Replacement Considerations
The NCP5173 serves as a direct functional substitute offering similar 1.5 A boost capabilities with an extended switching frequency range of 560 kHz to 1.0 MHz. Verify pin compatibility and inductor selection changes due to the frequency difference. Consult the manufacturer's cross-reference guide for final validation.
