The Texas Instruments TPS5420D is a high-output-current PWM converter designed for step-down voltage regulation. It integrates a low-resistance high-side N-channel MOSFET, enabling efficient operation with up to 95% efficiency.
This converter supports a wide input voltage range of 5.5V to 36V and can deliver up to 2A continuous output current (3A peak). The output voltage is adjustable down to 1.22V with 1.5% initial accuracy. It operates at a fixed 500kHz switching frequency, which helps in reducing the size of external filter components.
The TPS5420D is housed in a compact 8-pin SOIC package and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The device includes internal compensation to minimize external parts count and features system protection with overcurrent limiting, overvoltage protection, and thermal shutdown.
Key features include improved line regulation and transient response through input voltage feed-forward. The undervoltage-lockout circuit prevents start-up under insufficient input voltage conditions.
