Introduction

AI Translation

The MAX15062 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input voltage range. The converter delivers output current up to 300mA at 3.3V (MAX15062A), 5V (MAX15062B), and adjustable output voltages (MAX15062C). The device operates over the -40°C to +125°C temperature range and is available in a compact 8-pin (2mm×2mm) TDFN package. Simulation models are available. The device employs a peak-current-mode control architecture with a MODE pin that can be used to operate the device in 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 additionally skips pulses 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. The device also incorporates an EN/UVLO pin that allows the user to turn on the part at the desired input-voltage level. An open-drain RESET pin can be used for output-voltage monitoring.
