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