Product Description

The TPS63021DSJR is a High Efficient Single Inductor Buck-boost Converter with 4A switch that provide a power supply solution for products powered by either a two-cell or three-cell alkaline, NiCd or NiMH battery or a one-cell Li-ion or Li-polymer battery. The buck-boost converter is based on a fixed frequency, pulse width modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters power save mode to maintain high efficiency over a wide load current range. The power save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The maximum average current in the switches is limited to a typical value of 4A. The output voltage is programmable using an external resistor divider or is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery.
Up to 96% efficiency
3A Output current at 3.3V in step down mode (VIN = 3.6 to 5.5V)
More than 2A output current at 3.3V in boost mode (VIN >2.5V)
Automatic transition between step down and boost mode
Dynamic input current limit
Less than 50µA device quiescent current
Power save mode for improved efficiency at low output power
Forced fixed frequency operation at 2.4MHz and synchronization possible
Smart power good output
Load disconnect during shutdown
Over-temperature protection
Overvoltage protection
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
