MIC2155 Datasheet (Micrel Semiconductor) - PWM Synchronous Buck Controller

MIC2155, PWM Synchronous Buck Controller

The MIC2155 and MIC2156 are a family of two-phase, single-output synchronous buck control ICs featuring small size, high efficiency, and a high level of flexibility.

The ICs implement a 500kHz (MIC2155) and 300kHz (MIC2156) voltage mode PWM control, with the outputs switching 180° out of phase.
