Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM5007MMX/NOPB

LM5007MMX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM5007MMX/NOPB is a high-voltage synchronous buck switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 9 V to 75 V and delivers up to 500 mA output current. The device features a fixed 125 µs constant on-time architecture, supporting adjustable switching frequencies from 50 kHz to 800 kHz. Output voltages are programmable from 2.5 V to 73 V using external resistors. It includes integrated bootstrap diode and gate driver for the internal N-channel power MOSFET. The component functions within a temperature range of -40°C to +125°C TJ and is housed in an 8-pin VSSOP package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates high-side and low-side N-channel power MOSFETs with bootstrap diode for efficient synchronous rectification.
Utilizes constant on-time control architecture to ensure fast transient response and inherent cycle-by-cycle current limiting.
Features comprehensive protection mechanisms including thermal shutdown, undervoltage lockout, and hiccup mode overcurrent protection.
