The TPS63060DSCR is a high input voltage Buck-boost Converter with 2A switch current, provides a power supply solution for products powered by either three-cell up to six-cell alkaline, NiCd or NiMH battery or a one-cell or dual-cell Li-ion or Li-polymer battery. Output currents can go as high as 2A while using a dual-cell Li-Ion or Li-polymer battery and discharge it down to 5V or lower. 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 2.25A. The output voltage is programmable using an external resistor divider or is fixed internally on the chip.

• Up to 93% efficiency
• 2A at 5V (buck mode, VIN<10V), 1.3A at 5V (boost mode, VIN>4V) Output current
• Automatic transition between step down and boost mode
• <30µA Typical device quiescent current
• Fixed and adjustable output voltage options from 2.5 to 8V
• Power-save mode for improved efficiency at low output power
• Forced fixed-frequency operation at 2.4MHz and synchronization possible
• Power good output
• Buck-boost overlap control
• Load disconnect during shutdown
• Over-temperature protection
• Overvoltage protection
• Green product and no Sb/Br
