However, A1 pin should be connected to the most negative voltage of the application (even if diode “A1-K1” is not used). “SIGNAL” is clamped between positive “PS+” and negative “PS-“ power supplies. A1 pin must be connected to the negative power supply (even if diode “A1-K1” is not used). PS- A1 C1 A2 A1 C1 A2 C2 C3 A3 C4 A4 C2 C3 A3 PS+ C4 SIGNAL CHT-ELARA A4 Rectification function CHT-ELARA Full-bridge rectifier In this configuration, A1 pin should be connected to the rectified negative voltage. CHT-ELARA can also be used in applications where a positive and a negative power supplies are generated through a transformer.

The graph below indicates the junction-toair thermal resistance of the TDFP package mounted on PCB versus the surface of the copper thermal pads on the PCB. The designer should refer to this graph when designing his PCB layout, taking into account his own operating configuration: expected power dissipation and the maximum expected ambient operating temperature. 100 Junction-to-Ambient thermal resistance(°C/W) The tiny TDFP package used for CHTELARA requires adequate PCB layout in order to achieve efficient thermal dissipation, the minimization of the junction operating temperature, and maximizing the power dissipation taking advantage of the temperature behavior capability of CHTELARA. The junction-to-air overall thermal resistance of CHT-ELARA in TDFP package relies, to a large extend, on the implementation of the copper mounting pads that act as a heatsink for the integrated circuit. The design must take into consideration the size of the copper pad and its placement on either of the board surfaces, or both. 80 60 Ta = 25°C Still Air Polyimide board 40 20 0 0 1 2 3 4 5 6 Top& Bottom copper mounting pad area (cm2) PUBLIC Doc.
