MAX1750x Step-Down Converters
High-voltage, synchronous step-down DC-DC converter from Analog Devices
Analog Devices' MAX17501/MAX17502 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5 V to 60 V input voltage range. The MAX17501 delivers output currents up to 500 mA, while the MAX17502 delivers up to 1 A at output voltages of 0.9 V to 92% VIN. The output voltage is accurate to within ±1.7% over -40°C to +125°C. They are available in a compact, TDFN package.
The devices feature peak-current-mode control with pulse-width modulation (PWM). Users can choose devices with either pulse frequency modulation (PFM) or forced PWM scheme. PFM devices skip pulses at light load for higher efficiency, while forced-PWM devices operate with fixed switching frequency at any load for noise sensitive-applications. The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout.
A programmable soft-start feature allows users to reduce input inrush current. The device also incorporates an output enable/undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input-voltage level. An open-drain active-low RESET pin provides a delayed power-good signal to the system upon achieving successful regulation of the output voltage.
