LM2852YMXA-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXA-3.3/NOPB is a synchronous step-down DC/DC converter from Texas Instruments, part of the SIMPLE SWITCHER family. It delivers a fixed 3.3V output with a maximum continuous current of 2A. The device supports switching frequencies of 500kHz and 1500kHz, allowing optimization for efficiency or component size. It operates within an input voltage range of 2.85V to 5.5V. The integrated controller manages high-side and low-side N-channel MOSFETs. It is housed in a 14-pin HTSSOP package with an exposed thermal pad.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the ordering suffix matches /NOPB to ensure lead-free compliance and absence of halogenated flame retardants. Confirm the specific temperature grade and package variant align with design requirements. Cross-reference the manufacturer's latest datasheet for any updates to pinout definitions or electrical characteristics prior to finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator when a fixed 3.3V rail is required with up to 2A load capability. Choose the 500kHz setting for larger passive components but potentially higher efficiency at light loads. Opt for 1500kHz to minimize external inductor and capacitor sizes. Ensure the input source remains stable within the 2.85V to 5.5V window to maintain proper regulation and avoid undervoltage lockout conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2852 series of synchronous buck regulators designed for space-constrained applications. It integrates the controller and power switches into a single compact package. The SIMPLE SWITCHER architecture simplifies design implementation by reducing the number of external components needed compared to discrete solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2852YMXA-3.3 is a compatible alternative designation for the same functional device. LM2852XMXA-3.3/NOPB represents a variant with different switching frequency characteristics. Verify package compatibility and thermal performance when substituting with other members of the LM2852 family.
