ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TEA1210TS SSOP16 DESCRIPTION GENERAL DESCRIPTION TEA1210TS The TEA1210TS is a fully integrated DC/DC converter. Efficient, compact and dynamic power conversion is achieved using a novel digitally controlled concept like Pulse Width Modulation (PWM) or Pulse Frequency Modulation (PFM), integrated low R CMOS power switches with low parasitic capacitances, and fully synchronous rectification. The device operates at 600 kHz switching frequency which enables the use of external component...
