uP6101
5V/12V Synchronous-Rectified Buck Controller
General Description
The uP6101 is a compact synchronous-rectified buck controller specifically designed to operate from 5V or 12 supply
voltage and to deliver high quality output
voltage as low as 0.
6V (uP6101A) or 0.
8V (uP6101B/C).
This (P)SOP8 device operates at fixed 300kHz (uP6101A/B) or 200kHz (uP6101C) frequency and provides an optimal level of integration to reduce size and cost of the power supply.
This controller integrates internal
MOSFET drivers that support 12V+12V bootstrapped
voltage for high efficiency power conversion.
The bootstrap diode is built-in to simplify the circuit design and minimize external part count.
