MITSUBISHI HYBRID ICs M57120L HIGH VOLTAGE INPUT dc-dc CONVERTER MARKED SIDE A B D E H J F K L G M 1 C 12 TERMINAL NUMBER INPUT 11 5 OUTPUT Features: u Wide Range of Input Source Voltage (113V-400V DC) 12 PWM POWER 6 SUPPLY TP 7 Description: M57120L is a non-isolated DC-to-DC converter with a built-in transformer. Wide range of input voltage (DC 113V-400V) enables direct connection to rectified 120V and 240V AC. This device is best suited for use as a pre-regulator for standard DC-to-DC converters. u Built-in Surface-mount Transformer PWM CONTROLLER u SIP Structure Enables Efficient use of PCB Area GND 1 1 2 GND 2 Applications: u Power Source for Standard DC-to-DC Converters Outline Drawing and Circuit Diagram u Pre-regulator Dimensions Inches Millimeters Dimensions Inches Millimeters A 1.46 37.0 MAX G 0.16 4.0 MAX B 1.46 39.0 MAX H 0.37 9.5 MAX J 0.26 6.5 MAX K 0.1 2.54 C .63 D .18±.06 16.0 MAX 4.5±1.5 E .01±.01 0.35±0.2 L .2 F .02±.0.004 0.55±0.1 M 1.1 Ordering Information: M57120L 5.0 MAX 27.94 Sep.1998 MITSUBISHI HYBRID ICs M57120L HIGH VOLTAGE INPUT dc-dc CONVERTER Absolute Maximum Ratings, Ta = 25 °C unless otherwise specified Characteristics Symbol Test Conditions M57120L Units Input Voltage VIN 11, 12-1 pin 380 Volts Operating Temperature Topr There Should be -10 ~ +75 °C Storage Temperature Tstg No Condensation -20 ~ +85 °C Output Power POW – 4.4 Watts Electrical Characteristics, VIN = 280V, Ta = 25 °C unless otherwise specified Characteristics Symbol Test Conditions VIN Direct Current IB VIN = 113V – 5.4 6.0 mA VIN = 280V – 4.9 5.5 mA VIN = 380V – 5.3 5.9 mA Input Source Voltage Circuit Current Min. 113 Typ. 280 Max.
