| Description | The UTC UC3551 is a step-up DC/DC converter with high efficiency and low start-up voltage. It is operaded in stable waveforms without external compensate. This device incorporates an adaptive current ... |
| Features |
high switching rate which is up to 450 KHz, making the external component counts less required. Moreover, it features 17μA low quiescent current, which makes the battery life longer. The low start-up input voltage below 1V makes UTC UC3551 suitable for 1 to 4 battery cells applications of providing up to 300mA output current.
Two external resistors determine the value of the output voltage. The external power devices (NMOS or NPN) are derived by both internal 2A switch and driver.
The UTC UC3551 is intended to be used in PDA, DSC, LCD Panel, RF-Tags, MP3, portable instrument and wireless equip... |
