MIC2619YD6-TR IC REG BOOST ADJ 350MA TSOT23-6 Microchip Technology

 

General Description

The Micrel MIC26601 is a constant-frequency, synchronous buck regulator featuring a unique adaptive on-time control architecture. The MIC26601 operates over an input supply range of 4.5V to 28V and provides a regulated output of up to 6A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%, and the device operates at a switching frequency of 600kHz.
