Package
Pinout
The LM5116MH is housed in a 20-lead HTSSOP (Thermally Enhanced Thin Shrink Small Outline Package), which means it has 20 pins. These pins serve various functions, including:
1. VIN: Input supply voltage.
2. VCC: Internally regulated supply voltage.
3. UVLO: Undervoltage lockout setting.
4. EN: Enable pin.
5. RAMP: Ramp signal for modulation.
6. SS: Soft-start control.
7. RT: Timing resistor for switching frequency.
8. FB: Feedback input for voltage regulation.
9. COMP: Compensation network connection.
10. CS: Current sense input.
11. HO and LO: High-side and low-side driver outputs.
12. SW: Switch node connection.
13. GND: Ground.
14. BST: Bootstrap capacitor connection.
15. RES: Reset pin for the internal logic.
16. SYNC: Synchronization input.
17. DITH: Dithering control for EMI reduction.
18. AGND and PGND: Analog and power ground pins.
These functions enable the LM5116MH to efficiently control high-power DC-DC conversion processes.
