EG1165S

EG Micro · AC-DC Controllers And Regulators · SOP-16

EG1165S from EG Micro, in a SOP-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 REF5V power_out 5V reference output rated for 10 mA drive; a high-frequency ceramic bypass capacitor (1 µF suggested) should be placed close to this pin.
2 EN input Enable input with a 1.2 V comparison threshold (1.15 V to 1.25 V); below 1.2 V the chip enters standby and the 5V output is turned off.
3 SD input Shutdown input: high level turns PWM output off cycle-by-cycle (3 V minimum), low level allows PWM output; absolute maximum -0.3 V to 20 V.
4 SS input Soft-start pin; an external capacitor sets the soft-start time through its voltage rise rate, with an absolute maximum of -0.3 V to 5.5 V.
5 VSS power_in Chip signal (analog) ground for the control circuitry.
6 CP input Oscillator timing capacitor pin setting the switching frequency from 20 Hz to 500 kHz via f = 11.8×10^6 / CP (CP in pF); absolute maximum -0.3 V to 5.5 V.
7 ERRO output Output of the voltage-loop error amplifier; absolute maximum -0.3 V to 5.5 V.
8 FB input Inverting input of the voltage-loop error amplifier with a 1.2 V reference (1.188 V to 1.212 V); absolute maximum -0.3 V to 5.5 V.
9 SDLIN input Low-side MOS current comparator input with a 180 mV trip threshold referenced to COM; absolute maximum -0.3 V to +5 V.
10 LO output Drives the low-side power MOSFET gate; output limited to -0.3 V to VCC+0.3 V with peak source 1.5 A and sink 2 A (pulse width ≤10 µs).
11 COM power_in Power ground for the output driver stage; the low-side current-sense threshold is referenced to this pin.
12 VCC power_in Low-side supply pin with an operating range of 10 V to 20 V and an absolute maximum of -0.3 V to 20 V.
13 SDHIN input High-side MOS current comparator input with a 180 mV trip threshold referenced to VS; limited to VS-0.3 V to VS+5 V.
14 VS power_in High-side floating ground reference; limited to VB-20 V to VB+0.3 V.
15 VB power_out High-side floating bootstrap supply with an operating range of 10 V to 600 V and an absolute maximum of -0.3 V to 600 V.
16 HO output Drives the high-side power MOSFET gate; output limited to VS-0.3 V to VB+0.3 V with peak source 1.5 A and sink 2 A (pulse width ≤10 µs).
