PFM DC-DC boost IC NCP1406SNT1G step-up converter
The NCP1406SNT1G is a monolithic step-up DC-DC converter from ON Semiconductor that utilizes a Pulse Frequency Modulation (PFM) scheme with constant peak current control. This highly efficient power management IC integrates a 0.8A, 0.7Ω internal power switch and sensing resistor for inductor current monitoring, maintaining high efficiency across the entire load current range. With an input voltage range of 1.4V to 5.5V, it can be powered from a single lithium-ion battery or two alkaline cells, making it ideal for portable applications. The device can boost voltages up to 25V and deliver 1W of output power, suitable for biasing small and large OLED panels as well as driving series-connected white LEDs. The chip features an enable pin for user control to extend battery life during standby and supports pulse-width modulation for white LED applications.
Key Features
The NCP1406SNT1G offers several advanced features including low operating current of 15μA (when not switching) and extremely low shutdown current of just 0.3μA. It provides a typical startup voltage of 1.8V at 0mA load and includes built-in protection features such as output voltage soft-start, feedback pin open/short circuit protection, input undervoltage lockout, and thermal shutdown. The converter operates at a switching frequency up to 1.0 MHz and comes in a micro-miniature TSOP-5 package with a low-profile design that requires minimal external components.
Applications
The NCP1406SNT1G is designed for a variety of portable and power-sensitive applications including OLED bias supply, white LED drivers for backlighting, and power management in handheld devices. It's particularly suitable for personal digital assistants (PDAs), digital still cameras, cellular telephones, hand-held games, and various hand-held instruments. The converter's ability to generate high voltages from low-voltage sources makes it ideal for driving multiple series-connected LEDs or providing bias voltages for display panels in battery-powered equipment.
