TL1451ACPWR 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 Timing capacitor terminal for the on-chip adjustable oscillator, used together with RT.
2 RT passive Timing resistor terminal for the on-chip adjustable oscillator, used together with CT.
3 1IN+ input Non-inverting input of error amplifier 1, with a common-mode voltage range of 1.04 V to 1.45 V.
4 1IN- input Inverting input of error amplifier 1, with a common-mode voltage range of 1.04 V to 1.45 V.
5 1FEEDBACK passive Feedback/compensation node of error amplifier 1 in controller channel 1.
6 1DTC input Dead-time control input of the channel 1 comparator, which has no offset unless externally altered and can set 0% to 100% dead time.
7 1OUT output Uncommitted common-emitter output transistor of controller 1.
8 GND power_in Ground.
9 VCC power_in Supply voltage input; undervoltage lockout keeps the outputs off until the internal circuitry is operational.
10 2OUT output Uncommitted common-emitter output transistor of controller 2.
11 2DTC input Dead-time control input of the channel 2 comparator, which has no offset unless externally altered and can set 0% to 100% dead time.
12 2FEEDBACK passive Feedback/compensation node of error amplifier 2 in controller channel 2.
13 2IN- input Inverting input of error amplifier 2, with a common-mode voltage range of 1.04 V to 1.45 V.
14 2IN+ input Non-inverting input of error amplifier 2, with a common-mode voltage range of 1.04 V to 1.45 V.
15 SCP passive Short-circuit protection pin for the internal short-circuit protection function.
16 REF power_out Output of the internal regulator providing a stable 2.5-V reference supply.
