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)

**Overview** CTXS-5606S is a high-speed rectifier diode rated for 600 V and 60 A. The reverse recovery time (trr) has been optimized to 50 ns through lifetime control. The adoption of a high-current package ensures excellent heat dissipation. **Applications** - PFC circuits using CCM method - Secondary side rectifier diodes (flyback converters, resonant converters, etc.) - Freewheeling diodes (bridge circuits, offline buck, buck-boost converters, etc.) **Features** - Low loss - Ultra-fast - High heat dissipation package

New Japan Radio has started mass production of the "NJU9103," an analog front-end (AFE) with a built-in programmable gain amplifier (PGA) that is optimal for pressure gauges and flow meters, featuring a maximum gain of 512 times. 【Features】 1. Built-in PGA with a maximum gain of 512 times The NJU9103 incorporates two PGAs with gains of 128 times and 4 times, allowing for a combined amplification of 512 times. 2. Built-in D-A converter (DAC) for sensor offset correction The NJU9103 can reduce offset by generating a voltage opposite to the sensor's offset using the built-in DAC and adding it. 3. Reduction of board space through compact packaging 【Product Functions】 ● ADC resolution: 16 bits (No missing codes) ● Conversion data rate: 0.814 ksps to 6.51 ksps ● Input method: Differential/Single-ended/Pseudo-differential ● PGA: 1 time to 512 times ● Calibration function: Offset/Gain error calibration ● Conversion mode: Single conversion/Continuous conversion ● Interface: SPI (Serial Peripheral Interface) ● Package: ESON8-V1 (2.3mm x 2.3mm), SSOP8 (3.5mm x 6.4mm)

Sanken Electric has started selling the high-voltage three-phase brushless motor driver "SCM1270M Series," which incorporates a temperature monitoring function in the MIC. Since it can output an analog voltage corresponding to the MIC temperature, it enables control based on the heating situation by monitoring this temperature. The product lineup includes four models with 10A, 15A, 20A, and 30A in a DIP33 package. It has obtained UL certification (E118037) and is an environmentally friendly Pb-free product. It is ideal for applications such as washing machine drum drives and air conditioner compressor drives.
