EVALUATION KIT AVAILABLE MAX16956 36V, 300mA, Mini Buck Converter with 1.1µA IQ General Description Benefits and Features
The MAX16956 is a small, synchronous buck converter ● Integration and High-Switching Frequency Saves with integrated high-side and low-side switches. The Space device is designed to deliver up to 300mA with input • DC-DC Converter Up to 300mA Capability voltages from 3.5V to 36V, while using only 1.1µA • Fixed 5V/3.3V or Programmable Output-Voltage quiescent current at no load (fixed-output versions). Options (1V to 10V) Voltage quality can be monitored by observing the • Current-Mode-Control Architecture RESET signal. The device can operate near dropout by • 2.1MHz Operating Frequency running at 97% duty cycle, making it ideal for automotive • Fixed 5.4ms Internal Soft-Start applications under cold-crank. ● Spread-Spectrum Frequency Modulation Reduces The device offers fixed-output voltages of 5V and 3.3V, EMI Emissions as well as an adjustable version. The adjustable version allows the user to program the output voltage between ● Low IQ Enables Designers to Meet Stringent OEM 1V and 10V by using a resistor-divider. Frequency is fixed Module Power-Consumption Requirements at 2.1MHz, which allows for small external components, • 1.1µA Quiescent Current in Standby Mode reduced output ripple, and minimized AM radio interfer- (Fixed-Output-Voltage Versions Only) ence. The device offers both forced-PWM and skip modes ● Wide Input Voltage Range Supports Automotive of operation, with ultra-low quiescent current of 1.1µA Applications in skip mode. The device can be ordered with spread- spectrum frequency modulation designed to minimize • Operating VIN Range: 3.5V to 36V (42V Tolerant) EMI-radiated emissions due to the switching frequency. • 97% (Max) Duty-Cycle Operation with Low Dropout The MAX16956 is available in a small (3mm x 3mm) 10-pin µMAX® package and operates across the full auto- ● Robust Performance Supports Wide Range of motive temperature range of -40°C to +125°C. The device Automotive Applications is AEC-Q100 qualified. • Short-Circuit, Thermal Protections • -40°C to +125°C Automotive Temperature Range
