ISL97656IRTZ-TS2720 is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC REG. Review the specifications below when checking this part for your BOM.
The ISL97656IRTZ-TS2720 is a high-frequency, high-efficiency current mode control non-synchronous step-up voltage regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.2V to 6V and provides an adjustable output voltage up to 25V. The device supports a switch current of 3.8A and features selectable switching frequencies of 640kHz or 1.2MHz. It is housed in a 10-WFDFN exposed pad package and functions within a temperature range of -40°C to 85°C.
Verify the specific suffix TS2720 against official Renesas documentation to confirm exact marking and revision status. Confirm end-of-life or obsolescence status through authorized distributors as availability may be limited. Ensure compatibility with existing PCB footprints for the 10-TDFN-EP package before procurement.
Select this component when a compact, high-efficiency boost regulator is required for low-voltage input applications. Consider the 3.8A switch current limit and the two available switching frequencies for EMI and inductor size optimization. Verify that the non-synchronous design meets system efficiency requirements compared to synchronous alternatives.
This part belongs to the ISL97656 series of DC-DC switching regulators from Renesas (formerly Intersil). It is designed for space-constrained applications requiring reliable voltage boosting from single-cell lithium-ion batteries or similar low-voltage sources. The series emphasizes high frequency operation to minimize external component size.
Check for direct pin-compatible replacements within the Renesas portfolio. Evaluate alternative boost regulators with similar current ratings and input/output voltage ranges if this specific variant is unavailable.
