MB3759 Datasheet | Fujitsu Semiconductor Limited

DESCRIPTION The MB3759 is a control IC for constant-frequency pulse width modulated switching regulators. The IC contains most of the functions required for switching regulator control circuits. This reduces both the ponent count and assembly work. s FEATURES - - - - - - - Drives a 200 m A load Can be set to push-pull or single-end operation Prevents double pulses Adjustable dead-time Error amplifier has wide mon phase input range Built in a circuit to prevent misoperation due to low power supply voltage. Built in an internal 5 V reference voltage with superior voltage reduction characteristics s PACKAGES 16-pin plastic DIP 16-pin ceramic DIP 16-pin plastic SOP (DIP-16P-M04) (DIP-16C-C01) (FPT-16P-M06) MB3759 s PIN ASSIGNMENT (TOP VIEW) +IN1 1 16 +IN2 15 - IN2 14 VREF 13 OC 12 VCC 11 C2 10 E2 9 E1 (DIP-16P-M04) (DIP-16C-C01) (FPT-16P-M06) - IN1 2 FB 3 DT 4 CT 5 RT 6 GND 7 C1 8 s BLOCK DIAGRAM Output control OC 13 RT 6 CT 5 OSC T Q Q 8 9 C1 E1 = 0.2 V Dead time control DT 4 11 C2 10 E2 Error amp.1 +IN1 1 - IN1 2 +IN2 16 - IN2 15 + A1 - + - 12 VCC VREF GND PMW parator Reference regurator 14 7 A2 Error amp.2 Feed back MB3759 s ABSOLUTE MAXIMUM RATINGS Rating Parameter Power supply voltage Collector output voltage Collector output current Amplifier input voltage Plastic DIP Power dissipation Ceramic DIP SOP - Operating temperature Storage temperature Top Tstg PD Symbol VCC VCE ICE VI Condition Min - - - - Ta ≤ +25 °C Ta ≤ +60 °C Ta ≤ +25 °C - - - -...
