DESCRIPTION
The UTC UTC UC3552 is capable of converting a standard input of 3.3V to multiple outputs of 8V, − 8V , and 23V. Otherwise, filtering and loop performance are enhanced and facilitated by a high switching frequency of either 640 kHz or1.3MHz. As a power-smart design in shutdown mode a soft-start with an external capacitor that sets the input current ramp rate, reduces the current consumption to 0.1μA. A mere 2.6V input yields an impressive output voltage to 12V when operating.●
