Integrated Switch TPS62A01DRLR 50k+ in Stock

Creation Date

The TPS62A0x family of devices are synchronous step-down buck DC/DC converters optimized for high efficiency and compact design size. The devices integrate switches capable of delivering an output current up to 2 A. At medium to heavy loads, the devices operate in pulse width modulation (PWM) mode with 2.4-MHz switching frequency. At light load, the devices automatically enter power save mode (PSM) to maintain high efficiency over the entire load current range. In shutdown, the current consumption is minimal as well. The TPS62A0xA variants of this device family operate in forced PWM across the whole load current range.


 Features for the TPS62A01
  • 2.5-V to 5.5-V input voltage range
  • 0.6-V to VIN adjustable output voltage range
  • 180-mΩ and 120-mΩ low RDSON switches (1-A DRL)
  • 100-mΩ and 67-mΩ low RDSON switches (1-A DDC, 2-A)
  • < 23-µA quiescent current
  • 1% feedback accuracy (0°C to 125°C)
  • 100% mode operation
  • 2.4-MHz switching frequency
  • Power save mode or PWM option available
  • Power-good output pin
  • Short-circuit protection (HICCUP)
  • Internal soft start-up
  • Active output discharge
  • Thermal shutdown protection
  • Pin-to-pin compatible with the TLV62585 (DRL)
  • Pin-to-pin compatible with the TLV62569 (DDC)

The TPS62A0x devices provide an adjustable output voltage through an external resistor divider. An internal soft-start circuit limits the inrush current during start-up. Other features like overcurrent protection, thermal shutdown protection, and power good are built-in. The devices are available in a SOT563 and SOT23-6 package.
