NCV1406SNT1G

Voltage Regulators - DC DC Switching Regulators Overview

The NCV1406SNT1G is a monolithic step-up DC-DC converter manufactured by onsemi. It operates using a Pulse Frequency Modulation (PFM) scheme with constant peak current control. The device integrates an internal power switch rated at 0.8 A and includes a sensing resistor to monitor inductor current. It accepts an input voltage range of 1.4 V to 5.5 V and provides a single output capable of reaching up to 25 V. The maximum output current is specified at 25 mA. The component is housed in a 5-pin TSOP surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 0.8 A internal power switch for compact design
• Utilizes PFM control with constant peak current regulation
• Includes built-in inductor current sensing resistor

Voltage Regulators - DC DC Switching Regulators Applications

• Battery-powered portable devices requiring voltage boosting
• Low-power consumer electronics systems
• General-purpose DC-DC conversion in space-constrained designs

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NCV' indicates automotive qualification requirements compared to standard commercial variants. Confirm the 'SNT1G' suffix corresponds to the correct tape-and-reel packaging quantity and RoHS compliance status. Ensure the ordering part number matches the exact pinout and thermal specifications required for your PCB layout before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-component-count boost converter is needed for currents up to 25 mA. The integrated switch eliminates external high-current path components. Consider the 1.4 V minimum input voltage for compatibility with single-cell battery discharge curves. Evaluate the 25 V output limit against load requirements to ensure adequate headroom without exceeding device ratings.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the NCP1406 family of step-up converters. The 'N' prefix typically denotes automotive-grade reliability standards within onsemi's portfolio. It serves as a direct functional equivalent to the commercial NCP1406 variant, offering similar electrical performance but potentially with enhanced durability or testing protocols suitable for automotive environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The NCP1406SNT1G is the commercial counterpart. Verify if automotive qualification is strictly necessary; if not, the commercial version may be available. Check for updated revisions in the NCP1406 series that might offer improved efficiency or different packaging options while maintaining pin compatibility.
