MA5620

MA5620(Preliminary) 38V Synchronous Buck Controller With 2CH CC/CV  GENERAL DESCRIPTION The MA5620 is a synchronous buck controller. The device need externals high side and external low side power MOSFETs, and provides 5A of continuous load current and a wide input voltage of 8V to 38V. Current mode control provides fast transient response and cycle-by-cycle current limit. An internal soft-start prevents inrush current at turn-on, this device available in small TDFN-12L (3x3) package, provides a very compact solution with minimal external components.  FEATURES - Wide 8V to 38V Operating Input Range - Externals high side and low side Power MOSFET Switches - Output Adjustable from VFB(1.00V±2%) to 16V - Up to 95% Efficiency - Internal Soft-Start and Fixed 160KHz Frequency - Duty on ratio : 0% to 91% PWM control - Cycle-by-Cycle Over Current Protection - Input Under/Over Voltage Lockout  APPLICATION CIRCUIT VIN=8~32V C1 220μF 35V R5 10mΩ C7 10μF 35V x2 C4 0.1μF C6 0.1...
