Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | KFF | input | Voltage feed-forward programming pin with resistor to VIN controlling PWM ramp slope via internally divided current. |
| 2 | RT | input | Oscillator frequency programming pin with resistor to ground setting switching frequency and ramp charging current. |
| 3 | BP5 | power_out | 5-V internal reference output bypassed with 0.1-µF capacitor to ground, can supply up to 1 mA external load. |
| 4 | SYNC | input | External synchronization input (VIH = 2 V, VIL = 0.8 V) for oscillator frequency synchronization to external master clock. |
| 5 | SGND | power_in | Signal ground reference for the device. |
| 6 | SS/SD | input | Soft-start and shutdown programming pin with capacitor to ground charged by 2.3 µA current source, disabled at VSS/SD < 125 mV, enabled at VSS/SD > 210 mV, output ramp at 0.85-1.55 V. |
| 7 | VFB | input | Inverting input to error amplifier regulated to 0.700 V internal reference with tolerance of ±0.015 V over temperature. |
| 8 | COMP | output | Output of error amplifier serving as input to PWM comparator, internally clamped above ramp peak for improved large-signal transient response. |
| 9 | PGND | power_in | Power ground reference for the device with low-impedance connection to source of external power MOSFET. |
| 10 | LDRV | output | N-channel synchronous rectifier gate drive output that switches from BP10 voltage when MOSFET on to ground when MOSFET off. |
| 11 | BP10 | power_out | 10-V internal reference output for N-channel gate drive, bypassed with 1-µF ceramic capacitor to ground, can supply up to 1 mA external load. |
| 12 | SW | input | Switched-node connection used for overcurrent sensing in TPS40061 and zero-current sensing in TPS40060. |
| 13 | BPN10 | power_out | Negative 8-V reference output relative to VIN for high-side P-channel MOSFET gate drive, bypassed to VIN with 0.1-µF capacitor. |
| 14 | HDRV | output | Floating high-side P-channel MOSFET gate drive output that switches from VIN when MOSFET off to BPN10 when MOSFET on. |
| 15 | VIN | power_in | Main supply voltage input with operating range of 10 V to 55 V. |
| 16 | ILIM | input | Current limit programming pin with internal current sink setting voltage drop across external resistor to VIN, compared against high-side MOSFET voltage drop for overcurrent detection. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
