IL34063ADT from IKSEMICON, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SWC | output | Switch Collector. Collector of the internal high-current output switch transistor Q1. Rated to 40V and 1.5A switch current. Connected to the inductor/supply in step-up and voltage-inverting topologies. |
| 2 | SWE | output | Switch Emitter. Emitter of the internal output switch transistor Q1. Rated to 40V (with Vpin1 = 40V). Connected to the inductor/output diode in step-down topology or to ground return in step-up topology. |
| 3 | TC | passive | Timing Capacitor. External capacitor CT sets the oscillator on-time per CT = 4.5x10^-5 * ton. Typical values around 470 pF to 1.5 nF for the operating range up to 100 kHz. |
| 4 | GND | power_in | Ground return for the IC. Reference for VCC, comparator, oscillator and reference regulator. |
| 5 | CII | input | Comparator Inverting Input. Feedback sense input compared to the internal 1.25V reference (Vth typ 1.25V, 1.225-1.275V). Output voltage set by Vout = 1.25(1 + R2/R1). Input voltage range -0.3V to +40V, input bias current typically -40 nA. |
| 6 | VCC | power_in | Power supply input. Operating range 3.0V to 40V. Typical supply current 2.5 mA (max 4.0 mA) with CT = 1 nF. |
| 7 | Ipk Sense | input | Peak current sense input. Connected across an external current sense resistor RSC from VCC. Current-limit sense voltage is typically 300 mV (250-350 mV) between VCC and this pin; RSC ≈ 0.3 / IPK(switch). |
| 8 | DRC | output | Driver Collector. Collector of the internal driver transistor Q2. Rated 40V, driver collector current up to 100 mA. Tie to pin 1 for Darlington-connected output switch, or to VCC through a base-drive resistor for non-Darlington operation. |
