LM46002PWPT

Voltage Regulators - DC DC Switching Regulators Overview

The LM46002PWPT is a synchronous step-down voltage converter from Texas Instruments' SIMPLE SWITCHER family, housed in a 16-pin HTSSOP package. It accepts an input voltage range of 3.5 V to 60 V and provides a regulated output between 1 V and 28 V. The device delivers a maximum output current of 2 A with a typical quiescent current of 27 uA. It operates at a switching frequency up to 2.2 MHz and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix PWPT confirms the tape-and-reel packaging format upon ordering. Confirm that the HTSSOP-16 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your system's environmental specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60 V is required alongside a 2 A load capability. The adjustable frequency feature allows optimization for efficiency or size constraints. Consider the 16-pin HTSSOP package for surface-mount assembly needs. Evaluate the 27 uA quiescent current against standby power requirements for battery-operated applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SIMPLE SWITCHER series, designed for compact DC/DC conversion solutions. It shares architectural similarities with the LM46000 (0.5 A) and LM46001 (1 A) variants, offering higher current capacity. The device integrates control logic and power switches into a single IC, reducing the bill of materials compared to discrete designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM46000PWPT offers identical pinout and functionality with a reduced 0.5 A output current rating. LM46001PWPT provides a 1 A output current capability while maintaining the same interface and package. LM46002PWP is the tube-packaged equivalent of the same electrical specification.
