Description

DC/DC CTRL SYNC BUCK 500KHZ TDFN-8
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 x 2mm) TDFN package. Simulation models are available. The device employs a peak-current-mode control archi- tecture with a MODE pin that can be used to operate the device in pulse-width modulation (PWM) or pulse-fre- quency modulation (PFM) control schemes. PWM opera- tion provides constant frequency operation at all loads and is useful in applications sensitive to variable switch- ing 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.
