LM26420Q1XMHX/NOPB TI Dual Buck Regulator | 20-HTSSOP | 2A Output, 2.2MHz

Product Overview

The LM26420Q1XMHX/NOPB is a high-performance dual step-down (buck) switching regulator from Texas Instruments, designed for automotive and industrial applications. Housed in a 20-pin HTSSOP package with exposed pad for enhanced thermal performance, this device integrates two independent 2A output channels capable of delivering up to 4A total load current. With a wide input voltage range of 4.5V to 36V, it supports 12V and 24V battery systems commonly found in automotive environments. The regulator operates at a fixed 2.2MHz switching frequency, enabling small external components and reducing solution size. Its automotive qualification (AEC-Q100) ensures reliability under harsh conditions.

Detailed Technical Specifications

Key Features

• Dual 2A buck regulators with independent enable and soft-start
• Wide input voltage range: 4.5V to 36V (40V transient)
• High switching frequency (2.2MHz) minimizes external inductor and capacitor size
• Internal compensation and current-mode control for fast transient response
• Comprehensive protection: overvoltage, overcurrent, thermal shutdown, and undervoltage lockout
• AEC-Q100 qualified for automotive applications
• Low shutdown current (<2µA) for battery-powered systems
