SBmll BMBMPackage PFM Control SBBOOkRO 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. to 6.0 V in 0.1 V steps With the BM1601D, a step-up switching z DC/DC converter can be configured by using z an external coil, capacitor, and diode. The z built-in MOSFET is turned off by a protection z circuit when the voltage at the LX pin exceeds z the limit to prevent it from being damaged. This feature, along with t...
