Description

General part information

LM2775-Q1 Series

The LM2775-Q1 is a regulated switched-capacitor doubler that produces a low-noise output voltage. The LM2775-Q1 can supply up to 200 mA of output current over a 3.1-V to 5.5-V input range, as well as up to 125 mA of output current when the input voltage is as low as 2.7 V. The LM2775-Q1 provides a cost-optimized 5V, 200mA supply for powering CAN transceivers and other loads, boosting from a regulated 3.3-V system rail. It can be used as a post-boost in automotive systems that do not use a wide input voltage pre-boost or cold crank. At low output currents, the LM2775-Q1 can reduce its quiescent current by operating in a pulse frequency modulation (PFM) mode. PFM mode can be enabled or disabled by driving the PFM pin to high or low. Additionally, when the device is in shutdown, the user can chose to have the output voltage pulled to GND or left in a high impedance state by setting the OUTDIS pin high or low.

The LM2775-Q1 has been placed in TI’s 8-pin WSON, a package with excellent thermal properties that keeps the part from overheating under almost all rated operating conditions.
