Micro-packaged DC-DC converters

26 February 2003 Power Electronics / Power Management News & Events

ON Semiconductor, offers two new high frequency DC-DC converters with low-battery detectors for use in portable and wireless electronics.

The NCP1410 and NCP1411 are micro-powered, monolithic, pulse frequency modulation (PFM), step-up voltage-switching DC-DC converters. Both devices feature open drain low-battery detectors that help simplify power system design.

Configured for use in battery operated handheld electronics with up to 250 mA loading current, they deliver adjustable output voltages between 1,5 V and 5,5 V. A synchronous rectifier has been integrated into each device - improving power system efficiency, eliminating the need for external schottky diodes and reducing overall board space.

Delivering a high switching frequency of up to 600 kHz, they allow designers to use low profile inductor and output capacitors. Both devices include logic-controlled shutdown and 1 A cycle-by-cycle current limit features. To ensure quiet operation in discontinuous conduction mode and reduce EMI, an innovative 'ring-killer' feature has been added to the NCP1411.

The NCP1410 and NCP1411 DC-DC converters deliver an impressive power efficiency of 92% and a low quiescent supply current of 9 µA.
