MA5620
MA5620 is 38V Synchronous Buck Controller manufactured by Major Power Technology.
DESCRIPTION The MA5620 is a synchronous buck controller. The device need externals high-side and external low-side power MOSFETs, and provides higher than 5A continuous load current and a wide input voltage from 8V to 40V. 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 pact solution with minimal external ponents.  FEATURES - Wide 8V~40V Operating Input Range. - Externals high-side / low-side Power MOSFET Switches. - Output Adjustable : VFB (1.00V±2%). - Up to 97% Efficiency. - Internal Soft-Start and Fixed 160KHz Frequency. - Duty on ratio : 0% to 91% PWM control. - Cycle-by-Cycle Current Limit(or called Over Current Protection, OCP) - Thermal Shutdown Protection(or called Over Temperature Protection, OTP) - Input Under/Over Voltage Lockout.(UVLO/OVLO) - FB Over Voltage Protection.(OVP)  APPLICATION CIRCUIT EC1 220µF RS1 10mΩ C7 100n F C6 100n F R4 10Ω SENSE VIN SGND MA5620 PAD(GND) Q1 40N03 BS GH VREF P CS2 CS1 PGND FB Q2 40N04 C5 100n F C3 3.3n F R3 15kΩ CCS1 RCS2 RCS1 CCS2 10Ω 10Ω 22n F C4 100n F L1 33µ H/5.5A C1 10µ...
