ISL9111EHADJZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9111EHADJZ-T7A is a synchronous step-up DC-DC converter manufactured by Renesas Electronics Corporation. It operates with an input voltage range from 600 mV to 5.25 V and provides an adjustable output voltage between 2.5 V and 5.25 V. The device delivers a maximum output current of 240 mA at a fixed switching frequency of 1.2 MHz. Packaged in a compact SOT-23-6 form factor, it supports surface-mount installation and functions within an operating temperature range of -20°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as T7A indicate tape-and-reel packaging while other suffixes may denote cut tape or different reel quantities. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into manufacturing processes to ensure supply chain compatibility.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs prioritizing high efficiency in small footprints. Ensure the required output voltage falls within the 2.5 V to 5.25 V adjustable range. Verify that the load current does not exceed 240 mA and that the input source can maintain stability above the minimum 600 mV threshold during operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9111 series of synchronous boost converters designed for portable applications. It integrates power switches and control logic into a single chip, reducing the need for external Schottky diodes and simplifying the bill of materials compared to non-synchronous alternatives.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include ISL9111EH30Z-T7A (fixed 3.0 V output) and ISL9111EH33Z-T7A (fixed 3.3 V output). These variants share identical pinouts and electrical characteristics but offer fixed output voltages instead of adjustable regulation.
