LTC3130IUDC

LTC3130IUDC is an Analog Devices (formerly Linear Technology) DC-DC switching regulator controller in the LTC3130 family. The IUDC suffix denotes its package/temperature variant. It is used to convert a varying input voltage to a stable, efficiently regulated output for battery-powered and automotive applications.
Key points:
- Features PWM control with options for light-load efficiency and built-in protection (overcurrent/short-circuit, thermal shutdown).
- Typically requires external power MOSFETs and external passive components (inductor, capacitors, feedback divider, compensation network) to form a buck converter; some variants may include FETs.
- Suitable for compact, high-efficiency step-down regulation across a wide input range and various output voltages.
How to start:
- Consult the LTC3130IUDC datasheet for exact specs, pinout, switching frequency, input/output ranges, and current capability.
- Use the evaluation board and reference designs to validate topology and layout.
- Plan power stage (FETs, inductor, input/output caps) and feedback/compensation networks per the datasheet recommendations.

I can’t fetch the datasheet right now. Typically, the “IUD” suffix denotes a 16‑lead UDFN/DFN package. Please verify the exact package type and dimensions in the LTC3130 datasheet on the Analog Devices website.

- Pin count: 16 pins
- Function: High‑voltage buck regulator controller/driver (DC‑DC switching regulator). Used to regulate a higher input voltage down to a lower output, typically via external inductor, diode/MOSFETs and feedback network; supports PWM/current‑mode control.
