The NCP1403SNT1 is a monolithic PFM step-up DC-DC converter designed to boost voltages from a single Lithium or two AA/AAA cells up to 15 V, making it suitable for handheld applications. It features an internal MOSFET switch and offers efficiencies of 82% at 15 V output and 50 mA output current with a 5.0 V input, and 78% efficiency at 15 V output and 30 mA output current with a 3.6 V input. The device operates with a low current draw of 19 µA when not switching and has a shutdown current of just 0.3 µA, which helps extend battery life. The NCP1403SNT1 has a low startup voltage of 1.3 V and supports a PFM switching frequency of up to 300 kHz. It is packaged in a compact TSOP-5 format, which minimizes the need for external components. Typical applications include LCD biasing, personal digital assistants (PDAs), digital still cameras, handheld games, and handheld instruments. The product is available in both standard and Pb-free versions, with a tape and reel packaging option for efficient handling in production environments.
