The MAX17502 from Maxim is a high-efficiency, high-voltage, synchronous step-down DC-DC converter operating over a 4,5 V to 60 V input voltage range. Its wide input range makes it suitable for not only industrial control and building automation, but also base stations, telecom, home entertainment and automotive applications.
The chip delivers output currents up to 1 A over temperature at output voltages of 3,3 V and 5 V. The output voltage is accurate within ±1,6% over temperature. The device operates over the -40°C to +125°C industrial temperature range and is available in a 10-pin (3 x 2 mm) TDFN lead-free package with an exposed pad.
The MAX17502 features peak-current-mode control with pulse-width modulation (PWM). The PWM operation ensures constant switching frequency at all operating conditions. The low-resistance, on-chip, pMOS/nMOS switches ensure high efficiency at full load while minimising critical inductances, making the layout a simpler task compared to discrete solutions.
The IC offers fixed switching frequency of 600 kHz. To reduce input inrush current, it offers an adjustable voltage soft-start feature with an external capacitor from the SS pin to ground. The device also incorporates an output enable/under-voltage 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. The device supports hiccup-mode current-limit protection for low power dissipation under overload and output short-circuit conditions.
