The LTC1772BES6#TRPBF from LT is a constant frequency current mode step-down DC/DC controller designed for efficient power management. It provides excellent load and line regulation with a wide input voltage range from 2.5V to 9.8V.
Key features include a high operating frequency of 550kHz, which allows for the use of small external inductors, and a low dropout capability with 100% duty cycle operation. The device offers an output voltage accuracy of ±2.5% and can achieve efficiencies up to 94%. It also incorporates an accurate undervoltage lockout feature that shuts down the device when the input voltage falls below 2.0V.
In shutdown mode, the LTC1772BES6#TRPBF consumes a mere 8μA, maximizing battery life. The controller is available in a compact 6-lead TSOT-23 package, suitable for space-constrained applications. This controller is ideal for applications requiring high output currents and excellent transient response.
Applications include one or two Lithium-Ion-powered devices, cellular telephones, wireless devices, portable computers, and distributed power systems requiring 3.3V, 2.5V, or 1.8V outputs.
The input voltage range is 2.5V to 9.8V.
The operating frequency is a constant 550kHz.
The efficiency is up to 94%.
The package type is a 6-lead TSOT-23.
The operating temperature range is -40°C to 85°C.
The quiescent current is 270μA.
The shutdown current is 8μA.
