MAX1795EUA

Voltage Regulators - DC DC Switching Regulators Overview

The MAX1795EUA is a low-supply current step-up DC-DC converter manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 0.7 V to 5.5 V and provides an adjustable output voltage from 2 V to 5.5 V. The device delivers a maximum output current of 180 mA at a fixed switching frequency of 500 kHz. It features a true shutdown mode that reduces supply current to less than 1 µA. The component is housed in an 8-pin μMAX package and supports operation within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a synchronous rectifier for improved efficiency in step-up conversion applications.
• Provides true shutdown functionality to minimize power consumption during inactive periods.
• Utilizes a compact 8-pin μMAX surface-mount package suitable for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered devices requiring efficient voltage boosting
• Single-cell lithium-ion or alkaline battery systems
• Low-power consumer electronics with strict size limitations

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., T for tape-and-reel) against the required packaging format, as standard tube packaging may differ from reel options. Confirm RoHS compliance status for the exact orderable part number, as non-compliant variants exist without the plus sign. Check current availability status, as this component may be subject to limited stock or end-of-life restrictions depending on the distributor.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for boosting single-cell battery voltages. Ensure the load current requirements do not exceed the 180 mA limit. Verify that the desired output voltage falls within the 2 V to 5.5 V adjustable range. Consider the 500 kHz switching frequency for inductor size trade-offs compared to lower-frequency alternatives.
