Additional Infomation About Product

Datasheet Secondary power supply series for automotive 2.69 to 5.5V, 1.2V Output, 2.25MHz Synchronous Step-Down Converter BD90571EFJ-C General Description Key Specifications The BD90571EFJ-C is a synchronous rectification type Input voltage range 2.69V5.5 V step-down DC/DC converter with a 2.25MHz fixed Output voltage 1.2 V (Typ.) frequency that operates in with an input voltage range Output voltage accuracy 2.0 % (-40+125C) of 2.69V-5.5V. It has an integrated feedback resistor Operating frequency 2.25 MHz (Typ.) that supplies a fixed output voltage of 1.2V and a Maximum output current 1.0 A (Max.) phase compensation constant. Applications can be Circuit current at standby 0 A (Typ., 25C) created with a minimum of three external components. Moreover, the integrated Pch and Nch output MOSFET Operational temperature -40+125 C can supply a maximum output current of 1A. range Features Package Thanks to the integrated output feedback resistor HTSOP-J8 4.90 6.00 1.00 and phase compensation, applications can be created with a minimum of external components Excellent load response through current mode control Integrated Pch and Nch output MOSFET Integrated overcurrent protection with auto-reset Integrated output overvoltage detection/ short-circuit detection Integrated TSD and UVLO Light load mode/PWM fixation operation selection terminal Applications Automotive equipment Car audio and navigation TV Other electronic equipment 100 Typical application circuit 90 Light Load MODE 80 1.5 H 70 60 10 F 1F 47 F PWM MODE 50 40 30 20 VIN=5.0V 10 Figure 1 CIRCUIT 0 Figure 1.
