LM20136MHE

Texas Instruments · DC-DC Converters · HTSSOP-16-EP

LM20136MHE from Texas Instruments, in a HTSSOP-16-EP. 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 SS/TRK input Soft-start or tracking control input: an internal 5 µA source charges an external capacitor to set the soft-start ramp, an external source below 800 mV overrides the internal reference, and an open pin gives an internal 1 ms soft-start ramp.
2 FB input Feedback input to the inverting input of the internal transconductance error amplifier, with an 800 mV reference on the non-inverting input setting the closed-loop regulation voltage at this pin.
3 PGOOD output Open-drain power good output that indicates the output voltage is regulating within tolerance, and a 10 to 100 kΩ pull-up resistor is recommended for most applications.
4 COMP passive External compensation pin where a resistor and capacitor are connected to compensate the device.
5 NC unconnected Not internally connected; the datasheet requires this pin to be connected to GND to ensure proper operation.
6 PVIN power_in Input voltage to the internal power switches, with pins 6 and 7 connected together at the device and a low-ESR capacitor placed near these pins; operating range is 2.95 V to 5.5 V.
7 PVIN power_in Input voltage to the internal power switches, to be connected together with pin 6 at the device and decoupled by a low-ESR capacitor placed near these pins; operating range is 2.95 V to 5.5 V.
8 SW output Switch node; the PWM output of the internal power switches, to be connected together with pin 9.
9 SW output Switch node; the PWM output of the internal power switches, to be connected together with pin 8.
10 PGND power_in Power ground for the internal power switches, to be connected together with pin 11.
11 PGND power_in Power ground for the internal power switches, to be connected together with pin 10.
12 EN input Precision enable input whose turn-on threshold can be set with an external voltage divider; if not used, it should be connected to PVIN.
13 VCC power_out Output of the internal 2.7 V sub-regulator, which should be bypassed with a 1 µF ceramic capacitor.
14 AVIN power_in Analog input supply that generates the internal bias, which must be connected to PVIN through a low-pass RC filter.
15 AGND power_in Quiet analog ground for the internal bias circuitry.
16 SYNC input Frequency synchronization input: an external clock sets the switching frequency, and if grounded the device operates at approximately 410 kHz.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
