250mA output PFM Control Step-Up DC/DC Converter
BM1601D Series
INTRODUCTION
FEATURES
The BM1601D Series is CMOS PFM-control z step-up switching DC/DC converter. The PFM controller allows the duty ratio to be z
Low voltage operation: Startup at 0.8 V min. (IOUT = 1 mA) guaranteed Duty ratio: 66/78%, built in auto switching
automatically switched according to the load
type PFM controller
(light load: 66%, high output current: 78%), z External parts: Coil, capacitor, diode
enabling products with a low ripple over a wide z Output voltage: Settable to between 1.8V
range, high efficiency, and high output current.
