Product Details
Create a design and simulate using EE-Sim®: MAX17502
The MAX17502 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input voltage range. This device is offered in a fixed 3.3V, 5V, or adjustable output voltage (0.9V to 92%VIN) while delivering up to 1A of current. The output voltage is accurate to within ±1.7% over -40°C to +125°C. The MAX17502 is available in compact TDFN and TSSOP packages. Simulation models are available.
The device features peak-current-mode control with pulse-width modulation (PWM) and operates with fixed switching frequency at any load. The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout.
Applications
- Base Station, VOIP, Telecom
- Battery-Powered Equipment
- General-Purpose Point-of-Load
- Home Theater
- HVAC and Building Control
