LT1511

The LT1510 and LT1511 are high efficiency battery-charging chips capable of output powers up to 25W and 50W, respectively. These chips are intended for fast-charging batteries in modern portable equipment where space is at a premium. They are therefore packaged in low profile surface mount packages and run at a fairly high frequency (200kHz) to minimize the height and footprint of the complete battery charger. To minimize thermal resistance, these packages are specially constructed ...
