TEA1202TS is an integrated circuit from PHILIPS. It is a fully integrated battery power unit, including complete DC/DC converter circuit, two Low DropOut voltage regulators (LDOs) and a battery low detector.
The Philips TEA1202TS is a fully integrated battery power unit designed for use with 1-cell Nickel-Cadmium (NiCd), Nickel Metal Hybrid (NiMH), or Lithium-Ion batteries. It combines a high-efficiency DC/DC converter, two Low Dropout (LDO) voltage regulators, and a low battery detector into a single IC.
The device operates at a switching frequency of 600 kHz and supports both upconversion and downconversion modes. It includes internal power MOSFETs with low on-resistance and features synchronous rectification to maximize efficiency. The unit is suitable for applications such as cellular phones, cordless phones, and PDAs.
