MAX15462 Synchronous Step-Down DC-DC Converter
Analog Devices MAX15462 Synchronous Step-Down DC-DC Converter employs a peak-current-mode control architecture with a MODE pin. This pin can operate the device in the pulse-width modulation (PWM) or pulse frequency modulation (PFM) control schemes. PWM operation provides constant frequency operation at all loads and is useful in applications sensitive to variable switching frequency. PFM operation disables negative inductor current and skips pulse at light loads for high efficiency. The low-resistance on-chip MOSFETs ensure high efficiency at full load and simplify the PCB layout. To reduce input inrush current, the device offers an internal soft-start.
