BOOT 1 O A bootstrap capacitor is required between BOOT and PH. If the voltage on this capacitor is below the minimum required by the output device, the output is forced to switch off until the capacitor is refreshed. COMP 8 O Error amplifier output, and input to the output switch current comparator. Connect frequency compensation components to this pin. EN 3 I Enable pin, internal pullup current source. Pull below 1.2 V to disable. Float to enable. Adjust the input undervoltage lockout with two resistors. GND 9 — Ground PH 10 I The source of the internal high-side power MOSFET. PWRGD 6 O An open drain output, asserts low if output voltage is low due to thermal shutdown, dropout, overvoltage or EN shut down. RT/CLK 5 I Resistor Timing and External Clock. An internal amplifier holds this pin at a fixed voltage when using an external resistor to ground to set the switching frequency. If the pin is pulled above the PLL upper threshold, a mode change occurs and the pin becomes a synchronization input. The internal amplifier is disabled and the pin is a high impedance clock input to the internal PLL. If clocking edges stop, the internal amplifier is re- enabled and the mode returns to a resistor set function. SS/TR 4 I Slow-start and Tracking. An external capacitor connected to this pin sets the output rise time. Because the voltage on this pin overrides the internal reference, it can be used for tracking and sequencing. VIN 2 I Input supply voltage, 3.5 V to 60 V. VSENSE 7 I Inverting node of the transconductance (gm) error amplifier. PowerPAD 11 — GND pin must be electrically connected to the exposed pad on the printed circuit board for proper operation. |
