uP1561 - uPI Semiconductor

uP1561 Synchronous Buck Controller

Features The uP1561 is a high performance synchronous buck controller with 3A source/sink VTT LDO for memory systems power. It also provides the buffered low noise reference. The uP1561 has wide operation ranging from 3.0V to 26V for input power and 0.75V~3.0V for memory output voltage. The synchronous buck of the uP1561 adopts constanton-time PWM scheme t.

The uP1561 is a high performance synchronous buck controller with 3A source/sink VTT LDO for memory systems power. It also provides the buffered low noise reference. The uP1561 has wide operation ranging from 3.0V to 26V for input power and 0.75V~3.0V for memory output voltage. The synchronous buck of the uP1561 adopts constanton-time PWM scheme that features easy-to-use, low external component count, fast transient response and quasi- constant frequency operation over the operation range or in current mode to support ceramic output capacitors. The 3A source/sink VTT LDO has fast transient re.
