The LTC1772BES6#TRPBF from Analog Devices is a constant frequency, current mode step-down DC/DC controller designed for high efficiency and excellent regulation. It features a wide input voltage range from 2.5V to 9.8V and operates at a fixed frequency of 550kHz, allowing for the use of small external inductors.
This controller provides a ±2.5% output voltage accuracy and incorporates an accurate undervoltage lockout feature that shuts down the device when the input voltage falls below 2.0V. In shutdown mode, it consumes only 8µA, maximizing battery life. The device supports a 100% duty cycle for low dropout operation and can achieve efficiencies up to 94%.
The LTC1772BES6#TRPBF is available in a tiny 6-lead TSOT-23 package, making it suitable for space-constrained applications. Its current mode operation ensures excellent line and load transient response. This controller is ideal for applications requiring efficient power conversion, such as portable computers, wireless devices, and cellular telephones.
Key features include a constant 550kHz operation, low dropout capability, and a shutdown mode drawing only 8µA. The device is designed for positive output configurations and supports step-up, step-down, and step-up/step-down topologies.
