... For mechanical details of HVQFN32 package, see Chapter 12. 7 FUNCTIONAL DESCRIPTION 7.1 Introduction The TEA1211HN is able to operate in Pulse Frequency Modulation (PFM) or discontinuous conduction mode as well as in Pulse Width Modulation (PWM) or continuous conduction mode. All switching actions are completely determined by a digital control circuit which uses the output voltage level as control input ...

... N-down which is closed to prevent the coil from floating. 7.3 Adjustable output voltage The output voltage of the TEA1211HN can be set to a fixed value by means of an external resistive divider. After start-up through this divider, dynamic control of the output voltage is made possible by use voltage can be programmed from 1 ...

... In case no external synchronisation is necessary and the PWM-only option is not used, pin SYNC/PWM must be connected to ground. 7.11 Current limiter If the peak input current of the TEA1211HN exceeds its limit in PWM mode, current ramping is stopped immediately, and the next switching phase is entered. The SDA handbook, full pagewidth ...

... The (slave) address of the TEA1211HN is 0001 0000 (10h). The subaddress (or word address) is 0000 0000 (00h). The TEA1211HN acts as a slave receiver only. Therefore the clock signal SCL is only an input signal. The data signal SDA is a bidirectional line, enabling the TEA1211HN to send an acknowledge. ...
