Please leave the substrate assembly to us. If you provide the circuit and substrate design data, we will handle the mass production and delivery at our affiliated cooperative factory. 1. "Raw substrate supply" - We can provide only raw substrates based on your requirements. 2. "Substrate assembly mass production contract" - We will accept mass production contracts if you provide the circuit design and substrate design data. 3. "Substrate design mass production contract" - We will accept mass production contracts for substrate design during mass production if you provide the circuit design and data. 4. "Development mass production contract" - Upon receiving the product requirement specification from you, we will handle circuit design and substrate design development, as well as mass production contracts.

The NR264S is a synchronous rectification switching regulator IC that incorporates a power MOSFET. To achieve high efficiency under light load conditions, it operates in pulse skip mode during light loads. It operates stably with low ESR capacitors such as ceramic capacitors due to its peak current control method. It is equipped with comprehensive protection features including overcurrent protection, low input voltage protection, and thermal protection. 【Features】 - Synchronous rectification type - Operating modes Steady state: Current mode PWM control Light load: Pulse skip operation - Maximum efficiency (VIN = 12 V, VOUT = 5 V) Steady state: 94% Light load (Iout = 10 mA): 86% - Stabilizes output with low ESR ceramic capacitors - Reduces the number of external components (fixed output 5 V) - Allows setting of soft start time with external capacitors - Enable function - Frequency limitation function (limits pulse skip frequency at light load to 28 kHz) - Protection features Overcurrent protection (OCP): Latch type, automatic recovery Thermal shutdown protection (TSD): Automatic recovery Low input voltage malfunction prevention circuit (UVLO) Output short-circuit protection: Burst oscillation operation (Hiccup)
