TPS62230EVM-370

The TPS62230EVM-370 is an evaluation module helps the designers to evaluate the operation and performance of the TPS62230/1/2 devices. These devices are high efficiency, ultra small size, buck converters that switch at 3MHz. The TPS6223X device family is a high frequency synchronous step down DC to DC converter optimised for battery powered portable applications. It supports up to 500mA output current and allows the use of tiny and low cost chip inductors and capacitors. With a wide input voltage range of 2.05V to 6V the device supports applications powered by Li Ion batteries with extended voltage range. The minimum input voltage of 2.05V allows as well the operation from Li primary or two alkaline batteries. Different fixed output voltage versions are available from 1.0V to 3.3V. The TPS6223X series features switch frequency up to 3.8MHz.

• 3MHz switch frequency
• Up to 94% efficiency
• Output peak current up to 500mA
• Excellent AC and transientload regulation
• High PSRR (up to 90dB)
• Small external output filter components 1.0µH/ 4.7µF
• VIN range from 2.05V to 6V
• Optimised power save mode for low output ripple voltage
• Forced PWM mode operation
• 100% duty cycle for lowest dropout
