Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix CHGH6F against the manufacturer's official datasheet to confirm pinout compatibility and moisture sensitivity level (MSL) ratings. Ensure that the ordering information matches the exact package type and tape/reel specifications required for your assembly process. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1A output capability within a 6V maximum input system is required. The 2.2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 25uA quiescent current for battery life optimization. Verify that the SOT-563-6 footprint fits the PCB layout constraints and that the thermal performance meets the application's heat dissipation needs under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Richtek RT5760 series of synchronous buck converters. It shares the same core topology and functional block diagram as other variants in the family, such as the RT5760DHGH6F, but differs in specific packaging or minor parameter tolerances defined by the manufacturer. The series is characterized by its simplicity and ease of use for standard 5V or 3.3V rail generation tasks.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The RT5760DHGH6F is a documented variant within the same product line. Verify if the DHGH6F suffix indicates a different package or thermal rating than the CHGH6F version. Direct substitution requires confirming identical pin assignments and electrical characteristics via the official comparison matrix provided by Richtek.
