New Japan Radio Audio Amplifier "NJU8758"

Features - Wide input voltage range: 2.8V to 60V - Ultra-low quiescent current and low ripple Burst Mode operation: IQ = 9μA - 2A/60V power switch - Uses a single feedback pin to set either positive or negative output voltage - Programmable frequency (300kHz to 2MHz) - Can be synchronized with an external clock - Spectrum spreading modulation for low EMI - High efficiency supported by BIAS pin - Programmable under-voltage lockout (UVLO) - Improved thermal characteristics in a 10-pin 3mm x 3mm DFN package and a 16-pin MSOP package Overview The LT8362 is a current mode DC/DC converter with a built-in 60V, 2A switch, operating input voltage range of 2.8V to 60V. Its unique single feedback pin architecture allows for boost, SEPIC, or inverting configurations. With a quiescent current of only 9μA in Burst Mode operation, it maintains high efficiency at very low output currents while keeping standard output ripple below 15mV. Applications - Industrial and automotive equipment - Communication devices - Portable electronic devices

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)

Sanken Electric has developed the AC/DC converter IC "STR6A100MV/HVD series," which allows for switching between standby operating points. It automatically switches to PWM operation during normal operation and to burst operation during light load. With its comprehensive protection features, it enables the easy configuration of power supply systems with fewer components and high cost performance. It is ideal for white goods, office automation equipment, AV equipment, industrial equipment, and other SMPS applications.
