TEA1202TS Overview
GENERAL DESCRIPTION TEA1202TS The TEA1202TS is a fully integrated battery power unit including a high-efficiency DC/DC converter which runs from a 1-cell NiCd or NiMH battery, two low dropout voltage regulators and a low battery detector. The circuit can be arranged in many ways to optimize the application circuit of a power supply system. Therefore, most inputs and outputs are separated, the DC/DC converter can be...
