LTC3601EMSE#TRPBF

Analog Devices · DC-DC Converters · MSOP-16-EP

LTC3601EMSE#TRPBF from Analog Devices, in a MSOP-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 SW output Switch node output pin connected to the SW side of the external inductor, with a normal voltage swing from ground to PVIN.
2 SW output Switch node output pin connected to the SW side of the external inductor, with a normal voltage swing from ground to PVIN.
3 PGND power_in Power ground pin to which the negative terminals of the input bypass and output capacitors should be tied with a low impedance connection.
4 PGND power_in Power ground pin to which the negative terminals of the input bypass and output capacitors should be tied with a low impedance connection.
5 BOOST power_out Boosted floating driver supply pin whose normal swing ranges from a diode drop below INTVCC up to PVIN plus INTVCC, with the bootstrap capacitor connected between it and SW.
6 INTVCC power_out Internal 3.3V regulator output that should be decoupled to PGND with a low ESR ceramic capacitor of 1µF or more.
7 VON input On-time voltage input that sets the on-time comparator trip point, making on-time proportional to VOUT when VOUT is 6V or less, with a normal pin impedance of 180kΩ.
8 RT passive Oscillator frequency program pin where an external resistor between 80k and 400k to SGND sets switching from 800kHz to 4MHz, defaulting to 2MHz when tied to INTVCC.
9 FB input Output voltage feedback input to the error amplifier, which compares the feedback voltage to the internal 0.6V reference.
10 ITH passive Error amplifier output and switching regulator compensation pin, which should be connected to INTVCC to use the default internal compensation.
11 TRACK input Output voltage tracking and soft-start input where forcing a voltage below 0.6V overrides the internal reference, with an internal 1.4µA pull-up current from INTVCC.
12 RUN input Regulator enable pin where a voltage above 1.25V enables operation and a voltage below 1V places the part in shutdown, and it must not be left floating.
13 VIN power_in Main power supply input pin, operating from 4V to 15V, that should be closely decoupled to PGND with a low ESR capacitor of 10µF or more.
14 VIN power_in Main power supply input pin, operating from 4V to 15V, that should be closely decoupled to PGND with a low ESR capacitor of 10µF or more.
15 MODE/SYNC input Mode selection and external synchronization input that forces forced continuous operation when tied to ground and enables Burst Mode operation when floated or tied to INTVCC.
16 PGOOD output Open-drain power good output that is pulled to ground when the FB voltage is not within 8% (typical) of the internal 0.6V reference.
17 SGND power_in Signal ground exposed pad that must be soldered to the PCB for good thermal and electrical contact, with the feedback network, compensation network and RT resistor connected to this ground.
