6 / 16 page  6 LTC1267 LTC1267-ADJ/LTC1267-ADJ5 PI FU CTIO S CAP: Charge Compensation Pin. A capacitor to VCC pro- vides charge required by the PGate level shift capacitor during supply transitions. The charge compensation ca- pacitor must be larger than the gate drive capacitor. CT: External Capacitor. From this pin to ground sets the operating frequency. (The frequency is also dependent upon the ratio VOUT/VIN). ITH : Gain Amplifier Decoupling Point. The regulator cur- rent comparator threshold increases with the ITH pin voltage. SENSE – : Connects to internal resistive divider which sets the output voltage. The Sense– pin is also the (–) input of the current comparator. SENSE+: The (+) Input for the Current Comparator. A built-in offset between the Sense+ and Sense– pins, in conjunction with RSENSE, sets the current trip threshold. VFB1, 2: These pins receive the feedback voltage from an external resistive divider used to set the output voltage of the adjustable section. MSHDN: Master Shutdown Pin. Taking MSHDN high shuts down VCC and all control circuitry. SHDN1, 3, 5: These pins shut down the individual regula- tor control circuitry (VCC is not affected). Taking SHDN1, 3, 5 pins high turns off the control circuitry of adjustable 1, 3.3V, 5V sections and holds both MOSFETs off. Must be at ground potential for normal operation.
