# LM5013DDAR (Component) ## Description Buck Switching Regulator IC Positive Adjustable 1.2V 1 Output 3.5A 8-PowerSOIC (0.154", 3.90mm Width) The LM5013DDAR is a 100-V input, 3.5-A buck switching regulator IC that efficiently steps down high DC voltages (such as 24 V, 48 V, or battery rails) to lower regulated outputs. It is optimized for rugged environments where wide input variations and high reliability are required. It features ultra-low quiescent current operation, making it suitable for systems that require high efficiency even at light load or standby conditions. Key Features Wide input voltage range: 6 V to 100 V Up to 3.5 A output current capability Integrated 100-V high-side MOSFET Non-synchronous buck topology Ultra-low quiescent current (IQ) for high efficiency in standby Constant-on-time (COT) control for fast transient response No external compensation components required Adjustable output voltage (down to ~1.2 V reference) 50 ns minimum on/off time for high step-down ratios Built-in protection features: Overcurrent protection Thermal shutdown Input undervoltage lockout (UVLO) Open-drain power-good (PGOOD) signal for system monitoring Meets low EMI requirements (CISPR 25 Class 5 capable) Package 8-pin SO PowerPAD (DDA) surface-mount package Designed for good thermal performance in high-voltage applications Typical Applications Industrial power supplies (24 V / 48 V systems) Automotive power systems Telecom and networking equipment High cell-count battery systems Motor control and inverter subsystems #LM5013 #BuckConverter #DCDCConverter #TexasInstruments #PowerManagementIC #HighVoltageRegulator #3ARegulator #IndustrialPower #AutomotiveElectronics #SwitchingRegulator #COTController ## Component Details - **Owner:** adrian95 - **Created:** 6/15/2026 - **Last Updated:** 6/15/2026 - **Visibility:** Public - **Package or Case Code:** 8-powerSoic - **License:** https://creativecommons.org/licenses/by/4.0/ - **Symbol Style:** parametric-v1 - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/524b6a450a52e5e852f95c810d6c7b8c899bf7c1b5c33bba9a82499d324d039d.pdf - **Manufacturer Part Number:** LM5013DDAR - **Manufacturer Name:** Texas Instruments - **Part Type:** Linear Regulator - **Used in:** 6 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
