Overview
The TPS62006DGSR is a high-efficiency synchronous step-down DC-DC converter produced by Texas Instruments. This device is part of the TPS6200x family and is designed for low-power applications, offering high efficiency and low noise operation. It operates in a current-mode PFM/PWM scheme, switching between pulse width modulation (PWM) at moderate to heavy loads and pulse frequency modulation (PFM) at light loads to maintain high efficiency. The TPS62006DGSR is available in a 10-pin microsmall outline package (VSSOP) and has a wide operating temperature range of –40°C to 85°C.
