Chipower CE8377
The CE8377 is a CMOS PFM-control step-up switching DC/DC controller. The PFM controller allows the duty ratio to be automatically switched according to the load, enabling products with a low ripple over a wide range, high efficiency, and high output current. With the CE8377, a step-up switching DC/DC controller can be configured by using an external coil, capacitor, and diode.
