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

We have developed a common mode choke coil at Seiwa Electric. By using a new nano-crystal material for the core, we can achieve higher effectiveness. By switching to the nano-crystal common mode choke coil, it is possible to reduce the capacitance of surrounding capacitors, allowing for space-saving designs. (Nano-Crystal Core) This alloy has an ultra-fine crystalline grain structure, high saturation magnetic flux density, and excellent soft magnetic properties, making it suitable for applications related to noise, power supply, and communications. (Main Applications) - Noise-related: Noise filters (common mode chokes), zero-phase reactors, bead cores - Communication-related: Pulse transformers for LAN - Power supply-related: Switching power supplies, smoothing chokes, choke coils for active filters, cut cores for inverter transformers - Sensor-related: Current sensors, zero-phase current transformers, leakage circuit breakers - Pulse power-related: High-voltage pulse transformers - Others: Inverter transformers for vehicles (Features) - High saturation magnetic flux density - High permeability - Low core loss - Low magnetostriction (zero magnetostriction is also possible) - Good temperature characteristics - Small aging changes - Good high-frequency characteristics
