MCP16022MHz 500mA Synchronous PFM/PWM Buck Regulator w/Power Good | Evaluation Boards | 20 | Active | The MCP1602 is a high efficient, fully integrated 500 mA synchronous buck regulator with a power-good monitor. The 2.7V to 5.5V input voltage range and low quiescent current (45 µA, typical) makes the MCP1602 ideally suited for applications powered from 1-cell Li-Ion or 2-cell/3-cell NiMH/NiCd batteries.
At heavy loads, the MCP1602 operates in the 2.0 MHz fixed frequency PWM mode which provides a low noise, low output ripple, small-size solution. When the load is reduced to light levels, the MCP1602 automatically changes operation to a PFM mode to minimize quiescent current draw form the battery. No intervention is necessary for a smooth transition from one mode to another. These two modes of operation allow the MCP1602 to achieve the highest efficiency over the entire operating current range.
The open-drain power-good feature of the MCP1602 monitors the output voltage and provides indication when the output voltage is within 94% (typical) of the regulation value. The typical 2% hysteresis in the power-good transition threshold as well as a 262 ms (typical) delay time ensures accurate power good signaling.
The MCP1602 is available in either the 8-pin DFN or MSOP package. It is also available with either an adjustable or fixed output voltage. The available fixed output voltage options are 1.2V, 1.5V, 1.8V, 2.5V and 3.3V.
Additional protection features include: UVLO, overtemperature, and overcurrent protection. |

MCP16121.4MHz 1A Synchronous Buck Regulator | Voltage Regulators - DC DC Switching Regulators | 3 | Active | Microchip’s MCP1612 DC-to-DC converter offers the customer a compact and inexpensive method of efficiently converting battery and bus voltages to the lower voltages required by various circuits within their systems. This device is available in space efficient MSOP and DFN packages, and in the case of the DFN, thermally enhanced. Because the power FET and synchronous FET are integrated, minimal external components are required. Likewise, due to the high switching frequency, the requisite external inductor and capacitor can be minimized. Since the output voltage is adjustable with an external resistor divider, only the base device need be stocked to provide the customer with a multitude of output voltage variations. |
