During turn-on, the device requires an initial start up current (Icc) specified as “Turn-on Current”. Once operational, Icc will drop to the specified levels. 5. The DC-DC converter is guaranteed to start in 100 µs as long as the power supplies have the maximum turn-on current available for start up. Absolute Maximum Ratings 6,7 Parameter Absolute Maximum Max. Input Power 0.05 GHz 0.5 - 3.0 GHz +27 dBm +34 dBm VCC -0.5V ≤ VCC ≤ +6.0V Vin8 -0.5V ≤ Vin ≤ VCC + 0.5V Operating Temperature -40ºC to +85ºC Storage Temperature -65ºC to +125ºC 6. Exceeding any one or combination of these limits may cause permanent damage to this device. 7. M/A-COM does not recommend sustained operation near these survivability limits. 8. Standard CMOS TTL interface, latch-up will occur if logic signal is applied prior to power supply. Recommended PCB Configuration 9 9. Application Note S2083 is available on line at www.macom.com |
