Buck Switching Regulator IC Positive Fixed 5V 1 Output 1A SOT-23-6 The LMR50410Y5FQDBVRQ1 (part of the LMR50410-Q1 family from Texas Instruments) is a synchronous step-down (buck) DC-DC converter designed for automotive and industrial power applications. It operates over a wide input voltage range of 4 V to 36 V and can deliver up to 1 A output current, making it suitable for converting higher, unregulated voltages into stable lower voltages (e.g., 5 V or 3.3 V rails). The device integrates power switches, control circuitry, and compensation internally, allowing simple design with minimal external components and a compact PCB footprint. Key Features Power & Performance Wide input voltage range: 4 V to 36 V Output current: up to 1 A High switching frequency: 2.1 MHz (enables small inductors) High efficiency with PFM (light load) and FPWM (constant frequency) options Integration & Ease of Use Synchronous rectification (integrated high-side & low-side MOSFETs) Internal compensation (no complex external tuning) Minimal external components required Small SOT-23-6 package for compact designs Protection & Reliability Cycle-by-cycle current limit Short-circuit protection (hiccup mode) Thermal shutdown protection Undervoltage lockout (UVLO) ±1% reference voltage accuracy Automotive & Industrial Capability AEC-Q100 qualified (automotive grade) Operating temperature: Ambient: up to 125°C Junction: up to 150°C Designed for rugged automotive environments Additional Features Soft-start for controlled startup Precision enable pin for system control Monotonic startup with pre-biased output Available in fixed output (e.g., 5 V) variants Typical Applications Automotive electronics (ADAS, infotainment, lighting) Industrial power supplies Distributed power systems General-purpose DC-DC regulation #commonpartslibrary #integratedcircuit #powermanagement #voltageregulator
