Voltage Regulators - DC DC Switching Regulators datasheet and documents for RT9261-27GX

RT9261-27GX

Voltage Regulators - DC DC Switching Regulators Overview

The RT9261-27GX is a VFM Step-up DC/DC converter IC manufactured by Richtek USA Inc. It utilizes a CMOS process to achieve ultra-low supply current, making it suitable for battery-powered instruments. The device integrates an oscillator, VFM control circuit, driver transistor (LX switch), reference voltage unit, error amplifier, detection resistors, and LX switch protection. It constructs a low ripple and high efficiency step-up converter using only three external components: an inductor, a diode, and a capacitor.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Ultra-low input current consumption of 5µA at switch off
High output voltage accuracy with ±2% tolerance
Low start-up voltage capability of 0.85V at 1mA
Low temperature drift of +50 ppm/°C

Voltage Regulators - DC DC Switching Regulators Applications

Power source for battery-powered equipment
Power source for cameras, camcorders, VCRs, PDAs, pagers, electronic data banks, and hand-held communication equipment
Power source for applications requiring higher voltage than the batteries used in the appliances

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance and lead-free status as specified in official documentation. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly. Ensure the specific suffix matches the required package type and output voltage configuration before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs prioritizing minimal external component count and low quiescent current. It is appropriate for portable devices where battery life is critical. Ensure the application requires a fixed output voltage compatible with the -27 suffix. Verify that the load current does not exceed the internal switch capabilities without external assistance.

Voltage Regulators - DC DC Switching Regulators Part Context
