MB39A134 DC/DC Converter IC for Charging Li-ion Battery The MB39A134 is a DC/DC converter IC for charging Li-ion battery, which is suitable for down conversion, and uses pulse width modulation PWM for controlling the charge voltage and current independently. MB39A134 has a AC adapter detection comparator independent of the DC/DC converter controller, and can control the source of power supply to a system. It supports a wide input voltage range, enables low current consumption in standby mode, and can control the charge voltage and charge current with high precision, which is perfect for the built-in Li-ion battery charger used in devices such as notebook PC. • Support 2, 3 and 4 Cell Battery Pack • Built-in two constant current control loops • Built-in AC adapter detection function ACOK pin • Charge voltage accuracy Ta C to • Built-in charging voltage control without external setting resistor V/Cell or V/Cell Adjustable to charge voltage with external resistor • Built-in two high accurate current detection amplifiers 1% At input voltage difference 100 mV 5% At input voltage difference 20 mV Input offset voltage 0 mV Current Amp1 +3 mV Current Amp2 • Built-in Charging Current Control without external resistor RS 20 A Adjustable charging current with external resistor • Setting of switching frequency using an external resistor Frequency setting capacitor integrated 100 kHz to 2 MHz • Built-in under voltage lockout protection • In standby mode ICC 6 µA Typ , only AC adapter detection function is operated • Built-in VH regulator for reducing Qg loss of P-ch MOS FET • Package TSSOP-24 • Built-in charger for Notebook PC • Handy terminal device etc. • San Jose, CA 95134-1709 • 408-943-2600 MB39A134 Contents Description 1 Features 1 Applications 1 Pin Assignment 3 Pin Descriptions 4 Block Diagram 5 Absolute Maximum Ratings 6 Recommended Operating Conditions 7 Electrical Characteristics 8 Typical Characteristics 12 Functional Description 14 DC/DC Converter Block 14 Protection Functions 16 Transit Response When A Load Changes Suddenly 21 Connection Without Using The Current Amp1, Current Amp2 And The Error Amp1, Error Amp2 22 Input/Output Pin Equivalent Circuit Diagram 23 Typical Application Circuit 26 Application Note 30 Reference Data 39 Usage Precaution 41 Ordering Information 41 RoHS Compliance Information 41 Package Dimension 42 Document History 43 Sales, Solutions, and Legal Information 44 Page 2 of 44 Pin Assignment TOP VIEW −INC1 OUTC1 ADJ1 COMP1 ACOK VREF ACIN COMP2 ADJ2 OUTC2 CELLS BATT +INC1 ADJ3 COMP3 +INC2 STF024 MB39A134 Page 3 of 44 MB39A134 Pin Descriptions Pin No. Pin Name I/O -INC1 I Current detection amplifier Current Amp1 inverted input pin.
