The CN5318 is a simple, compact PFM boost controller designed for applications where extremely low cost and small size are top priorities. The output voltage can be adjusted by the external resistor divider with 1% feedback voltage accuracy from an input voltage range of +2.7V to +6.5V.
Low current consumption of 32uA typical makes CN5318 ideal for battery-powered applications.
The CN5318 is designed specifically to provide a simple application circuit and minimize the size and number of external components, making them ideal for consumer electronics applications.
The CN5318 adopts PFM operating mode, which provides excellent efficiency over a wide-range of input voltage and load currents. The on-time and off-time are tuned to permit optimization of external component size.
Chip enable input can make CN5318 into ultra-low-current shutdown mode.
The CN5318 is available in a space-saving 6-pin SOT23 package.
