LT8610IMSE#PBF

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

LT8610IMSE#PBF 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 SYNC input External clock synchronization input that must be grounded for Burst Mode operation at low loads, tied to a clock or to INTVCC for pulse-skipping mode, and never left floating; a DC voltage of 3V or higher is needed for pulse-skipping.
2 TR/SS passive Output tracking and soft-start pin where a voltage below 0.97V forces FB to follow it, an internal 2.2µA pull-up sets the output ramp rate, and it is pulled to ground through 230Ω during shutdown and fault conditions.
3 RT passive A resistor connected between RT and ground sets the switching frequency.
4 EN/UV input Shuts the LT8610 down when low and enables it when high, with a hysteretic threshold of 1.00V rising and 0.96V falling, and it is tied to VIN if shutdown is not used.
5 VIN power_in Supply pin for internal circuitry and the internal top power switch that must be tied together with pin 6 and locally bypassed.
6 VIN power_in Supply pin for internal circuitry and the internal top power switch that must be tied together with pin 5 and locally bypassed.
7 PGND power_in Power switch ground that is the return path of the internal bottom-side power switch and must be tied together with pin 8.
8 PGND power_in Power switch ground that is the return path of the internal bottom-side power switch and must be tied together with pin 7.
9 SW output Output of the internal power switches that must be tied together with pins 10 and 11 and connected to the inductor and boost capacitor, with a small PCB node.
10 SW output Output of the internal power switches that must be tied together with pins 9 and 11 and connected to the inductor and boost capacitor, with a small PCB node.
11 SW output Output of the internal power switches that must be tied together with pins 9 and 10 and connected to the inductor and boost capacitor, with a small PCB node.
12 BST power_out Provides a drive voltage higher than the input voltage to the top power switch and requires a 0.1µF boost capacitor placed as close to the IC as possible.
13 INTVCC power_out Internal 3.4V regulator bypass pin with maximum output current of 20mA that must not be loaded externally and needs at least a 1µF low ESR ceramic capacitor to power ground.
14 BIAS power_in Supplies the internal regulator instead of VIN when tied above 3.1V, and it should be tied to VOUT for output voltages of 3.3V and above.
15 PG output Open-drain power-good output that remains low until FB is within ±9% of the regulation voltage with no fault condition, and is valid when VIN is above 3.4V.
16 FB input Feedback pin regulated to 0.970V that receives the feedback divider tap and a phase lead capacitor (typically 4.7pF to 10pF) connected to VOUT.
17 GND power_in Exposed pad ground that must be connected to the negative terminal of the input capacitor and soldered to the PCB to lower thermal resistance.
