ONSEMI MC34166D2TR4G Switching Regulator
The MC34166 series are high-performance fixed frequency switching regulators designed for dc-to-dc conversions, including step-down, inverting, and step-up applications. They feature an internal temperature compensated reference, a 72 kHz oscillator with on-chip timing, a latching pulse width modulator, a high-gain error amplifier, and a high-current output switch capable of over 3.0A. Protective features include cycle-by-cycle current limiting, undervoltage lockout, thermal shutdown, and a low power standby mode. Available in surface-mount D²PAK and TO-220 packages, these devices are suitable for automotive, industrial, and consumer electronics requiring efficient and reliable voltage regulation.
