Key Featrues
High Efficiency of 85% (Vin = 2.0 V, VOUT = 3.0 V, 70 mA): The converter achieves up to 85% efficiency under typical operating conditions, significantly reducing power loss and improving battery life. This makes it ideal for energy-sensitive applications like portable audio players, digital cameras, and handheld instruments.
Low Operating Current of 30 µA (VOUT = 1.9 V): With a low quiescent current, the NCP1402 minimizes power consumption during standby or low-load conditions. This feature is particularly beneficial for devices like pagers and PDAs, where extended battery life is critical.
Chip Enable Power Down Capability: The integrated chip enable feature allows the converter to be powered down when not in use, further reducing power consumption and extending battery life. This is especially useful for applications like electronic games and cellular telephones, where power management is essential.
Only Three External Components Required: The NCP1402 simplifies circuit design by requiring only three external components, reducing board space and manufacturing complexity. This makes it an excellent choice for compact devices such as camcorders and digital cameras, where space is at a premium.
Applications
