TL1454ACPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CT | passive | Oscillator timing capacitor connection, paired with RT to GND; the datasheet recommends a 10% or better NPO ceramic with a recommended range of 10 pF to 4000 pF. |
| 2 | RT | passive | Oscillator timing resistor connection to GND, with a recommended range of 5.1 kΩ to 100 kΩ for an oscillator frequency of 50 kHz to 2 MHz. |
| 3 | DTC1 | input | Channel 1 dead-time control input that sets the maximum duty cycle, with threshold 1.1 V at 0% and 0.5 V at 100% duty cycle; soft start is implemented by a capacitor between REF and DTC. |
| 4 | IN1+ | input | Channel 1 noninverting error-amplifier input, with common-mode input voltage limited to −0.2 V to 1.45 V and an absolute maximum of 23 V. |
| 5 | IN1− | input | Channel 1 inverting error-amplifier input, with common-mode input voltage limited to −0.2 V to 1.45 V and an absolute maximum of 23 V. |
| 6 | COMP1 | output | Channel 1 error-amplifier output used for loop compensation, with DC loading limited to 45 µA source current and a recommended sink current of 100 µA maximum. |
| 7 | GND | power_in | Network ground; all device voltages are referenced to this pin. |
| 8 | OUT1 | output | Channel 1 totem-pole MOSFET driver output for n-channel step-up or flyback converters, rated for ±40 mA output current and 20 V output voltage. |
| 9 | OUT2 | output | Channel 2 totem-pole MOSFET driver output for p-channel step-down or inverting converters, rated for ±40 mA output current and 20 V output voltage. |
| 10 | VCC | power_in | Supply voltage input, with a recommended range of 3.6 V to 20 V and an absolute maximum of 23 V. |
| 11 | COMP2 | output | Channel 2 error-amplifier output used for loop compensation, with DC loading limited to 45 µA source current and a recommended sink current of 100 µA maximum. |
| 12 | IN2− | input | Channel 2 inverting error-amplifier input, with common-mode input voltage limited to −0.2 V to 1.45 V and an absolute maximum of 23 V. |
| 13 | IN2+ | input | Channel 2 noninverting error-amplifier input, with common-mode input voltage limited to −0.2 V to 1.45 V and an absolute maximum of 23 V. |
| 14 | DTC2 | input | Channel 2 dead-time control input that sets the maximum duty cycle, with threshold 1.1 V at 0% and 0.5 V at 100% duty cycle. |
| 15 | SCP | input | Short-circuit protection node; a capacitor to GND sets the time-out, and the latch sets when it charges to 1 V, with the latch resetting when VCC falls to 2 V or less or the capacitor is discharged. |
| 16 | REF | power_out | 1.26 V reference output that can source a maximum of 1 mA for external loads, with a 0.047 µF to 0.1 µF ceramic capacitor to GND recommended. |
