Features

to control current mode switched mode power supplies, this family has the following improved features. Start up current is guaranteed to be less than 0.5 mA. Oscillator discharge is trimmed to 8.3 mA. During under voltage lockout, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5 V. The difference between members of this family are shown in the table below. PART NUMBER UC2842A UC2843A UC2844A UC2845A UVLO ON 16 V 8.5 V 16 V 8.5 V UVLO OFF 10 V 7.9 V 10 V 7.9 V MAXIMU.
