Synchronous 1MHz 1.5A Step-Down Voltage Regulator The LM3100 Synchronously Rectified Buck Converter features all functions needed to implement a highly efficient, cost effective buck regulator capable of supplying 1.5 A to loads with voltages as low as 0.8 V. Dual 40 V N-Channel synchronous MOSFET switches allow for low external component thus reducing complexity and minimizing board space. The LM3100 is designed to work exceptionally well with ceramic and other very low ESR output capacitors. The Constant ON-Time (COT) regulation scheme requires no loop compensation, results in fast load transient response, and simplifies circuit implementation. Through the use of a unique design the regulator does not rely on output capacitor ESR for stab... |

2.5-A Step-Down Voltage Regulator The LM3102 Synchronously Rectified Buck Converter features all required functions to implement a highly efficient and cost-effective buck regulator. The device can supply 2.5 A to loads with an output voltage as low as 0.8 V. Dual N-channel synchronous MOSFET switches allow a low component count, thus reducing complexity and minimizing board size. Different from most other COT regulators, the LM3102 does not rely on output capacitor ESR for stability, and is designed to work exceptionally well with ceramic and other very low-ESR output capacitors. The device requires no loop compensation, results in a fast load transient response and simple circuit implementation. The operating frequency rem... |
