Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input supply voltage for the IC; operating range is 4.5 V to 75 V absolute maximum 76 V. |
| 2 | EN | input | Enable input with tri-level control: below 0.4 V shutdown, 0.4 V to 1.2 V standby mode, above 1.2 V operational, with 5-µA internal pull-up current. |
| 3 | SS | input | Soft start input; internal 11-µA current source charges external capacitor, with 1.2 V reference and 120 mV clamp above FB voltage. |
| 4 | RAMP | output | Ramp generator output; external 100 pF to 2000 pF capacitor connected to GND sets emulated current ramp slope for peak current mode control. |
| 5 | RT/SYNC | input | Oscillator frequency set and synchronization input; internal resistor to GND programs switching frequency 50 kHz to 1 MHz, external sync pulse width less than 150 ns. |
| 6 | GND | power_in | Ground return; signal and power ground reference for the controller. |
| 7 | COMP | output | Error amplifier output; internal 60 dB gain amplifier with 3 MHz unity-gain bandwidth, loop compensation network connected between COMP and FB pins. |
| 8 | FB | input | Feedback signal input to inverting input of error amplifier with 1.205 V regulation threshold and ±18 nA maximum input bias current. |
| 9 | OUT | input | Output voltage sensing input; connect directly to regulated output voltage to provide VIN-VOUT feedback for ramp generator compensation. |
| 10 | RES | output | Restart timer output for hiccup mode (LM5088-2 only); external capacitor sets restart delay with 50-µA charge and 25-µA discharge current sources, 1.2 V upper and 0.2 V lower thresholds. |
| 11 | CSG | power_in | Current sense ground; low-side reference terminal for external current sense resistor connected between CS and CSG pins. |
| 12 | CS | input | Current sense input measuring re-circulating diode current with internal sample-and-hold circuit and 120 mV cycle-by-cycle current limit threshold. |
| 13 | SW | output | Switching node output; connect directly to source terminal of external MOSFET switch and free-wheeling diode anode. |
| 14 | HG | output | High-side gate driver output; 1.5 A peak source and 2 A peak sink current with 12 ns rise and 6 ns fall time driving external MOSFET gate. |
| 15 | BOOT | passive | Bootstrap capacitor connection; external 0.022 µF minimum ceramic capacitor required between BOOT and SW pins, charged from VCC via internal diode. |
| 16 | VCC | power_out | Bias regulator output; 7.8 V typical regulation from VIN with 30 mA internal current limit, requires 0.1 µF to 10 µF ceramic decoupling capacitor. |
| 17 | EP | passive | Exposed thermal pad; electrically isolated must be soldered to ground plane to reduce thermal resistance per thermal analysis recommendations. |
