The TPS563300 is a high-efficiency, easy-to-use
synchronous buck converter with a wide input voltage range of 3.8 V to 28 V, and
supports up to 3-A continuous output current and 0.8-V to 22-V output voltage.
The device employs fixed-frequency peak current
control mode for fast transient response and good line and load regulation. The optimized
internal loop compensation eliminates external compensation components over a wide range of
output voltage and operation frequency. Pulse frequency modulation (PFM) mode maximizes the
light load efficiency. The low quiescent current feature is beneficial for long battery life
time in low-power operation. The device also has a frequency spread spectrum feature, which
helps with lowering down EMI noise.
The device provides complete protections including OTP, OVP, UVLO, cycle-by-cycle OC limit, and UVP with hiccup mode. This device is in a small SOT583 (1.6-mm × 2.1-mm) package with 0.5-mm pin pitch, and has an optimized pinout for easy PCB layout and promotes good EMI performance.
