TL1451ACDR

Texas Instruments · AC-DC Controllers And Regulators · SOIC-16

TL1451ACDR from Texas Instruments, in a SOIC-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, which runs at 500 kHz maximum.
2	RT	passive	Timing resistor terminal for the on-chip adjustable oscillator, which is set by terminating RT and 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	output	Feedback terminal of error amplifier 1 for PWM control loop compensation.
6	1DTC	input	Dead-time control input of comparator 1, which 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 comparator 2, which can set 0% to 100% dead time.
12	2FEEDBACK	output	Feedback terminal of error amplifier 2 for PWM control loop compensation.
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 terminal for the internal short-circuit protection circuit.
16	REF	power_out	Output of the internal regulator providing a stable 2.5-V reference supply.
