LV5681P-E

LV5681P-E is a special purpose voltage regulator manufactured by Sanken Electric Co., Ltd. This product is a buck-boost type DC-DC converter with a nominal input voltage of 10 V - 40 V and an output voltage of 0.7V to 40V. It is encapsulated in the slim SOP-8L package, with a low profile height of only 0.94 mm, suitable for a wide range of applications.

The LV5681P-E offers a wide range of features, including an integrated low on-resistance power MOSFET, adjustable output voltage using an external resistor divider, and transition time control using a proprietary clock synchronization technique. It also features a power-save mode, operating frequency range at 150 kHz, soft start, over-voltage protection, over-voltage limiting, and over-current protection. With a low quiescent current of 0.5 μA and a low shutdown current of 125 nA, the LV5681P-E is ideal for power sensitive applications such as cameras, digital photo frames, mobile phones, and digital audio players.

The LV5681P-E\'s low profile SOP-8L packaging provides a cost-effective solution for space-constrained applications, making it suitable for portable devices. The small package size also reduces the number of external components, resulting in a compact design. In addition, its high switching frequency of 150 kHz provides low electromagnetic interference (EMI) noise, low EMI filter costs, and high efficiency.

The LV5681P-E has a wide input voltage range and is capable of supplying 2 A peak output currents. It can operate in a wide temperature range from -20°C to 85°C, making it suitable for use in harsh environments. The device is also protected from over-voltage, over-current, and short circuit conditions.

The LV5681P-E utilizes a buck-boost topology, which provides stable and accurate output voltages. Its internal power MOSFET offers low rDS(on) for high efficiency. The internal clock synchronization technique helps to minimize the transition time, eliminating the need for external compensation components.

The operating modes of LV5681P-E are boost (step-up), buck (step-down), and buck-boost (step-up/down). The buck-boost mode allows the device to operate as a buck regulator without the need to change the direction of the switch, providing significant benefits such as improved efficiency and reduced size.

In summary, the LV5681P-E is a highly integrated, low quiescent current, and low shutdown voltage voltage regulator with a wide input voltage range, suitable for powering a wide range of power sensitive applications in a small and cost-effective package. With its low profile height, high efficiency, low output ripple, and over-current and over-voltage protection, it is an ideal choice for both consumer and industrial applications.
