MAX887HESA
MAX887HESA - Brand New Maxim Integrated DC Switching Regulators
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The MAX887 high-efficiency, step-down DC-DC converter provides an adjustable
output from 1.25V to 10.5V. It accepts inputs from 3.5V to 11V and delivers
600mA. Operation to 100% duty cycle minimizes dropout voltage (300mV typ at
500mA). Synchronous rectification reduces output rectifier losses, resulting
in efficiency as high as 95%.
Fixed-frequency pulse-width modulation (PWM) reduces noise in sensitive
communications applications. Using a high-frequency internal oscillator allows
tiny surface-mount components to reduce PC board area, and eliminates audio-
frequency interference. A SYNC input allows synchronization to an external
clock to avoid interference with sensitive RF and data acquisition circuits.
