LM2596HVGDP-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596HVGDP-ADJ is a monolithic integrated circuit step-down switching regulator designed for high-efficiency power conversion. It supports an adjustable output voltage range of 1.2V to 37V with a maximum guaranteed output current of 3.0A. The device operates with a wide input voltage range and utilizes a fixed internal oscillator frequency of 150kHz. This specific variant features a TO-263 (D2PAK) surface-mount package, facilitating compact PCB layouts while maintaining robust thermal performance for demanding applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated 150kHz fixed-frequency internal oscillator enables the use of smaller external filter components compared to lower-frequency regulators.
• TTL shutdown capability allows for low-power standby mode operation with minimal quiescent current consumption.
• Built-in thermal shutdown and current limit protection circuits ensure device reliability under abnormal operating conditions.

Voltage Regulators - DC DC Switching Regulators Applications
