denotes the specifications which apply over the full internal operating temperature range (Note 2). Specified as each individual output channel at TA = 25°C, VIN1 = VIN2 = 12V, unless otherwise noted per the typical application shown in Figure 24. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
RPGOOD PGOOD Pull-Down Resistance 1mA Load 20 Ω VINTVCC Internal VCC Voltage VIN1 = VIN2 = 3.6V to 20V 3.1 3.3 3.5 V VINTVCC Load Reg INTVCC Load Regulation ICC = 0mA to 50mA 1.3 % fOSC Oscillator Frequency 1 MHz fSYNC Frequency Sync Range With Respect to Set Frequency ±30 % IMODE MODE Input Current MODE = INTVCC –1.5 µA
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
See output current derating curves for different VIN, VOUT and TA. may cause permanent damage to the device. Exposure to any Absolute
Note 4:
100% tested at wafer level. Maximum Rating condition for extended periods may affect device
Note 5:
This IC includes overtemperature protection that is intended reliability and lifetime. to protect the device during momentary overload conditions. Junction
Note 2:
The LTM4622 is tested under pulsed load conditions such that temperature will exceed 125°C when overtemperature protection is active. TJ ≈ TA. The LTM4622E is guaranteed to meet performance specifications Continuous operation above the specified maximum operating junction over the 0°C to 125°C internal operating temperature range. Specifications temperature may impair device reliability. over the full –40°C to 125°C internal operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM4622I is guaranteed to meet specifications over the full –40°C to 125°C internal operating temperature range. Note that the maximum ambient temperature consistent with these specifications is determined by specific operating conditions in conjunction with board layout, the rated package thermal resistance and other environmental factors.
