174 / 182 page  174 8048B–AVR–03/09 ATtiny43U 26. Errata The revision letter in this section refers to the revision of the ATtiny43U device. 26.1 ATtiny43U 26.1.1 Rev. C • Increased Probability of Boost Converter Entering Active Low Current Mode 1. Increased Probability of Boost Converter Entering Active Low Current Mode The boost converter may enter and stay in Active Low Current Mode at supply voltages and load currents higher than those specified. This is due to high switching currents in bonding wires of the SOIC package. Devices packaged in MLF are not affected. Problem Fix / Workaround Add a 1.5nF capacitor between pins LSW and GND of the SOIC package. Also, increase the value of the by-pass capacitor between pins V CC and GND to at least 30µF. Alternatively, use the device in MLF, without modifications. 26.1.2 Rev. B Not sampled. 26.1.3 Rev. A Not sampled. |
