NCP1450ASN50T1G Description

Short technical summary and product information.

The NCP1450ASN50T1G from ON Semiconductor is a PWM step-up DC-DC switching controller designed for portable applications powered by one or two battery cells. This device features a low startup voltage of 0.9 V typical and can operate down to 0.6 V. It offers high efficiency, reaching up to 88% at specific load conditions, and can deliver high output currents up to 1000 mA.

 

The controller operates at a fixed frequency of 180 kHz and includes an enable pin for power-down functionality to extend battery life. It is housed in a low-profile, micro-miniature TSOP-5 package (SOT-23-5 Thin, TSOT-23-5), making it suitable for space-constrained designs. The NCP1450A series supports standard regulated output voltages including 1.9 V, 2.7 V, 3.0 V, 3.3 V, and 5.0 V, with additional voltages available upon request.

 

With only six external components required, this series provides a simple means to implement highly efficient converters for large output current applications. Typical applications include Personal Digital Assistants (PDAs), electronic games, portable audio devices, digital still cameras, and handheld instruments.
