A charge pump is a type of DC-to-DC converter that raises or lowers voltage by storing energetic charge in capacitors. Charge-pump circuits are electrically simple circuits that can achieve high efficiencies, sometimes as high as 90–95%.
A type of DC-DC converter known as a charge pump circuit, also known as a charge pump regulator, uses switched-capacitor techniques to either raise or lower an input voltage level.
Most power-supply ICs’ main function is regulation. These gadgets produce a regulated output voltage from an uncontrolled input voltage. Simply expressed, despite fluctuating input voltage or output current, these ICs offer an output voltage that doesn’t fluctuate.
The Global Charge pump IC market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A low-noise output voltage is produced by the controlled switched-capacitor doubler known as the LM2775-Q1. When the input voltage is as low as 2.7 V, the LM2775-Q1 can produce up to 125 mA of output current and up to 200 mA of output current throughout a 3.1-V to 5.5-V input range, respectively.
The LM2775-Q1 boosts from a controlled 3.3-V system rail to produce a cost-effective 5V, 200mA supply for powering CAN transceivers and other loads. In automotive systems that don’t use a broad input voltage pre-boost or cold crank, it can be used as a postboost.
Pulse frequency modulation (PFM) mode operation allows the LM2775-Q1 to minimise its quiescent current at low output currents.
The PFM pin can be driven high or low to enable or disable PFM mode. Additionally, the user can choose to have the output voltage pulled to GND or left in a high impedance condition by setting the OUTDIS pin high or low when the device is in shutdown.
