●The TPS61200EVM-179 is an evaluation module for TPS61200 low input voltage synchronous boost converter. The TPS61200 device provide a power supply solution for products powered by either a single cell, two cell, or three cell alkaline, NiCd or NiMH, or one cell Li Ion or Li polymer battery. It is also used in single cell fuel cell or solar cell battery applications where the input voltage is as low as 0.3V. The TPS61200EVM-179 operates from a 0.3V to 5.5V (starts up 0.5V) input rail and provides a single output voltage up to 5.5V. Once the input voltage is connected and verified, connect the EN pin to VBAT at JP1. The converter starts up and regulates to the set output voltage. The boost converter is based on a fixed frequency, PWM controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters the Power Save mode to maintain a high efficiency over a wide load current range.
● Startup into full load at 0.5V input voltage
● Adjustable output voltage from 1.8V to 5.5V
● Switch current limit of 1.5A (max)
● More than 90% efficiency
● 600mA output current at 3.3V (VIN >= 1.2 V)
● 600mA output current at 5V (VIN >= 3.3 V)
● Quiescent current of less than 55µA
●This device has limited built in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
●It is important to operate EVM within input voltage of 0.3V to 5.5V and output voltage of 1.8V to 5.5V. Exceeding specified input range may cause unexpected operation and irreversible damage to EVM.
