Product Details
The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. The MAX17760 is a high-efficiency, high-voltage, Himalaya synchronous step-down DC-DC converter with integrated MOSFETs operating over an input-voltage range of 4.5V to 76V. The device can deliver up to 300mA current. Output voltage is programmable from 0.8V up to 88% of input voltage (VIN). Built-in control loop compensation eliminates the need for external components.
The MAX17760 features a peak-current-mode control architecture. The device can be operated in either the forced pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes. Forced PWM mode provides constant frequency operation at all loads for frequency sensitive applications, while PFM mode provides superior light-load efficiency by skipping pulses. The device integrates an open drain active-low RESET output voltage monitor, adjustable input undervoltage lockout (EN/UVLO) and programmable soft-start. The feedback voltage regulation accuracy over -40°C to +125°C is +1.6% to -1.7%. The MAX17760 is available in a compact 12-pin (3mm x 3mm) TDFN package. Simulation models are available.Applications
- Industrial Control Power Supplies
- General Purpose Point-of-Load
