Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM5009AMMX/NOPB

LM5009AMMX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM5009AMMX/NOPB is a non-synchronous buck regulator from Texas Instruments designed for wide input voltage applications. It operates with an input range of 9.5V to 95V and delivers up to 150mA output current. The device utilizes a constant on-time (COT) control architecture, eliminating the need for external compensation networks. Key electrical parameters include a switching frequency of 600kHz, adjustable output voltage between 2.5V and 85V, and a quiescent current of 485µA. It is housed in an 8-pin VSSOP package and supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Constant on-time control architecture simplifies design by removing the need for external compensation components.
Wide input voltage capability allows direct connection to high-voltage buses without pre-regulation.
Integrated bootstrap diode reduces external component count and board space requirements.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AMM' against the official datasheet to confirm temperature grade and package variant accuracy. Ensure the component status is current, as availability may vary. Cross-reference the manufacturer part number directly with the latest documentation to avoid discrepancies in pinout or electrical specifications during procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for high-input voltage environments requiring simple control loops. The COT topology offers fast transient response without stability compensation challenges. Consider the 150mA limit for load requirements and ensure adequate thermal management for the VSSOP package under continuous operation conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5009 family of wide-input buck converters. It shares architectural similarities with other TI high-voltage regulators but is distinct in its non-synchronous design and specific COT implementation. The family targets industrial and automotive sectors where robustness and simplified design are prioritized over maximum efficiency at light loads.
