series introduction
# Introduction to the NCP698SQ28T1G Product Series
## 1. Overview
The NCP698SQ28T1G product series represents a cutting - edge solution in the field of power management integrated circuits (PMICs). These devices are engineered to meet the diverse and demanding power requirements of modern electronic systems, offering a high - level of performance, efficiency, and reliability.
## 2. Key Features
### 2.1 High - Efficiency Power Conversion
- The NCP698SQ28T1G series is designed with advanced power conversion topologies. It can achieve high conversion efficiencies, which is crucial for reducing power losses and heat generation in electronic devices. This high efficiency not only helps in extending the battery life of portable devices but also reduces the overall energy consumption of larger systems, making it an environmentally friendly choice.
- For example, in applications where power is at a premium, such as in battery - powered IoT devices, the high - efficiency power conversion of this series ensures that the device can operate for longer periods between charges.
### 2.2 Wide Input Voltage Range
- These PMICs support a wide input voltage range. This flexibility allows them to be used in a variety of power sources, from low - voltage battery supplies to higher - voltage DC power sources. For instance, it can handle input voltages from a few volts up to a relatively high value, making it suitable for different types of battery chemistries (such as lithium - ion, nickel - metal hydride) as well as power adapters.
- This wide input voltage range also provides design flexibility for engineers, enabling them to use the same PMIC in multiple product designs with different power source requirements.
### 2.3 Multiple Output Channels
- The NCP698SQ28T1G series typically offers multiple output channels. Each output channel can be independently regulated, allowing it to supply different voltage levels to various components within an electronic system. For example, in a smartphone, one output channel can provide the core voltage for the processor, while another can supply the voltage for the display or other peripheral components.
- The ability to have multiple regulated outputs simplifies the power supply design of complex electronic systems, reducing the need for multiple discrete power regulators.
### 2.4 Integrated Protection Features
- To ensure the safety and reliability of the connected electronic components, the series is equipped with a comprehensive set of protection features. These include over - voltage protection (OVP), under - voltage protection (UVP), over - current protection (OCP), and thermal shutdown protection.
- Over - voltage protection prevents the output voltage from exceeding a safe level, which could damage sensitive components. Under - voltage protection ensures that the device operates within a specified voltage range. Over - current protection limits the current flowing through the device to prevent overheating and component failure. Thermal shutdown protection automatically shuts down the device when the temperature exceeds a safe threshold, protecting it from damage due to excessive heat.
### 2.5 Low Quiescent Current
- The NCP698SQ28T1G devices have a low quiescent current. Quiescent current is the current consumed by the PMIC when it is in a standby or idle state. A low quiescent current is essential for battery - powered devices, as it helps to conserve battery power during periods of inactivity.
- For example, in a wearable device that spends most of its time in a low - power standby mode, the low quiescent current of this PMIC series ensures that the battery drain is minimized, resulting in longer battery life.
## 3. Applications
### 3.1 Portable Electronic Devices
- In smartphones, tablets, and smartwatches, the NCP698SQ28T1G series can be used to manage the power supply
