LT3800EFE#PBF

Analog Devices · DC-DC Controllers · TSSOP-16-EP

LT3800EFE#PBF from Analog Devices, in a TSSOP-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 VIN power_in Converter input supply; the IC operates from 4V to 60V input with UVLO start-up threshold of 7.5V.
2 NC unconnected No connection.
3 SHDN input Precision shutdown pin with 1.35V rising enable threshold and 120mV hysteresis; pulling it below 0.7V puts the IC in low-current shutdown with IVIN below 10μA.
4 CSS input Soft-start AC coupling capacitor input, connected in series with a 200k resistor to VOUT, with 2μA average current setting the output startup slew rate; shorting it to SGND disables soft-start.
5 BURST_EN input Burst Mode and reverse-current inhibit enable: below 0.5V both functions are enabled, and reverse-current inhibit is disabled above 2.5V.
6 VFB input Error amplifier inverting input connected to the internal 1.231V reference through a resistive divider from VOUT, with 25nA typical input bias current.
7 VC passive Error amplifier output corresponding to peak switch current per cycle, which must not be pulled low with a low-impedance source and should be bypassed by at least 100pF; external manipulation requires a 1kΩ series resistance.
8 SENSE- input Negative input of the current sense amplifier, with inductor current limit set at ±150mV across the SENSE inputs.
9 SENSE+ input Positive input of the current sense amplifier, with inductor current limit set at ±150mV across the SENSE inputs.
10 PGND power_in High-current ground reference for the synchronous switch, whose return path must not corrupt SGND.
11 BG output Synchronous switch gate drive output.
12 VCC power_out Internal regulator output powering most IC functions, decoupled with a low ESR 1μF capacitor to PGND; driving it externally reduces VIN pin current to 20μA.
13 NC unconnected No connection.
14 SW passive Reference for the VBOOST supply and high-current return for the bootstrapped switch.
15 TG output Bootstrapped switch gate drive output.
16 BOOST power_in Bootstrapped supply with maximum operating voltage up to 75V (ground referred), decoupled with a low ESR 1μF capacitor to SW.
17 SGND power_in Exposed package backside low-noise ground reference that must be soldered to the PCB ground.
