... TEA1202TS SSOP20 2000 Jun 08 GENERAL DESCRIPTION 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 ...

... LX2 20 inductor connection 2 FUNCTIONAL DESCRIPTION Control mechanism The TEA1202TS DC/DC converter is able to operate in PFM (discontinuous conduction) or PWM (continuous conduction) operating mode. All switching actions are completely determined by a digital control circuit which uses the output voltage level as its control input. This novel ...

... In low output power situations, the TEA1202TS will switch over to PFM (discontinuous conduction) operating mode. In this mode, regulation information from an earlier PWM operating mode is used. This results in optimum inductor peak current levels in the PFM mode, which are slightly larger than the inductor ripple current in the PWM mode ...

... Battery power unit External synchronization and PWM-only mode If an external high-frequency clock or a HIGH level is applied to pin SYNC/PWM, the TEA1202TS will use PWM regulation independent of the load applied. In the event a high-frequency clock is applied, the switching frequency in the PWM mode will be exactly that frequency divided by 22 ...

... Philips Semiconductors Battery power unit External component selection I L1 NDUCTOR The performance of the TEA1202TS is not very sensitive to inductance value. The best efficiency performance over a wide load current range is achieved by using an inductance of 6.8 H e.g. TDK SLF7032 or Coilcraft DO1608 range.
