Product Overview

The LTC1772CS6#PBF is a constant frequency current-mode step-down DC/DC Controller providing excellent AC and DC load and line regulation. The device incorporates an accurate under voltage lockout feature that shuts down the LTC1772 when the input voltage falls below 2V. It provides a ±2.5% output voltage accuracy and consumes only 270µA of quiescent current. For applications where efficiency is a prime consideration, it is configured for burst mode operation, which enhances efficiency at low output current. To further maximize the life of a battery source, the external P-channel MOSFET is turned on continuously in dropout (100%dutycycle). In shutdown, the device draws a mere 8µA. High constant operating frequency of 550kHz allows the use of a small external inductor.
  • High output currents easily achieved
  • Burst mode operation at light load
  • Current mode operation for excellent line and load transient response
  • Shutdown mode draws only 8µA Supply current
  • ±2.5% Reference accuracy
