MA5624-2CH CC/CV 30V Synchronous Buck Controller


MA5624-30V Synchronous Buck Controller With 2CH CC/CV DataSheet

MA5624 DEMO SCH

MA5624 BOM

GENERAL DESCRIPTION
    The MA5624 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 30V. 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-23L (4x4) package, provides a very compact solution with minimal external components.

FEATURES
- Wide 8V to 30V Operating Input Range
- Internals high side and low side Power MOSFET Switches
- Output Adjustable : VFB(1.00V±2%)
- 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
