TPS54061 Step-Down DC-DC Converter
Wide input 60 V, 200 mA converter with Low IQ
Texas Instruments' TPS54061 device is a 60 V, 200 mA, synchronous step-down DC-DC converter with integrated high side and low side MOSFETs. Current mode control provides simple external compensation and flexible component selection. The non-switching supply current is 90 µA. Using the enable pin, shutdown supply current is reduced to 1.4 µA. To increase light load efficiency, the low side MOSFET emulates a diode when the inductor current reaches zero. Under voltage lockout is internally set at 4.5 V, but can be increased using two resistors on the enable pin.
Features
- Integrated high side and low side MOSFET
- Diode emulation for improved light load efficiency
- Peak current mode control
- 90 µA operating quiescent current
- 1.4 µA shutdown supply current
Applications
- 4 mA to 20 mA current-loop powered sensors
- Low power standby or bias voltage supplies
- Industrial process control, metering, and security systems
- High efficiency replacement for high voltage linear regulators
