Description
LM5032MTCX/NOPB is TI’s high-voltage, fixed-frequency, current-mode PWM controller intended for off-line isolated switching supplies (e.g., LED drivers, AC-DC adapters). It does not include a power MOSFET; an external MOSFET is required. Key features include a high-voltage startup/current source, wide input range, current-sense PWM control, soft-start, and comprehensive protections (UVLO, OVP, IOL/short-circuit, OTP/over-temperature). The MTCX suffix indicates a 16-pin package (MSOP/HTSSOP family), and NOPB signifies RoHS-compliant (lead-free). Typical applications are flyback and buck/boost converters in LED lighting and offline power supplies, where simple, low-component-count designs with good protection are needed. For exact electrical specs, pinout, and application notes, refer to the TI LM5032 datasheet.
Equivalent
There isn’t a one-to-one cross for LM5032MTCX/NOPB. Closest TI substitutes are other LM503x family parts: LM5030, LM5031, and LM5033 (high-voltage, current‑mode flyback/LED driver controllers). For third‑party options with similar function, consider On Semiconductor’s NCP125x/NCP136x families (high‑voltage flyback controllers).
Features
Key features of LM5032MTCX/NOPB (concise):
- High-voltage, constant-current LED driver with integrated switch for LED strings
- External sense resistor sets LED current (programmable via reference)
- Wide input voltage range suitable for automotive/general lighting
- Open-LED and short-LED protection with fault handling
- Overcurrent, overtemperature, and undervoltage lockout protection
- Soft-start to minimize inrush and hot-plug effects
- Dimming support: PWM dimming and DC dimming control
- Fault/status reporting for easy optimization and monitoring
- Compact 8-pin MTCX package; Pb-free (NOPB) options available
Note: Exact electrical specs (voltage range, current range, pin functions) vary by revision; refer to the datasheet for detailed numbers and recommended application circuitry.
