The MP4562 is a configurable-frequency step-down converter with an integrated high-voltage high-side MOSFET (HS-FET). It provides 2A of output capability, with up to a 60V input power supply.
Peak current mode control with internal compensation provides fast transient response and easy loop design. The device operates from a wide 4.5V to 60V input voltage (VIN) range and wide 100kHz to 2.5MHz switching frequency (fSW) range, which accommodates a variety of step-down applications with high efficiency and optimized size.
Full protection features include cycle-by-cycle current limiting and short-circuit protection (SCP) with frequency foldback, which protect against overload and short-circuit conditions, even while VIN is high. The frequency stretch down function improves efficiency and reduces the output voltage (VOUT) ripple.
The MP4562 is available in a space-saving TSOT23-8 package.
