HM5309
Description
The HM5309 is a simple, pact PFM boost controller designed for applications where extremely low cost and small size are top priorities. The output voltage is fixed at 9V with 1% accuracy from an input voltage range of +2.7V to +6.5V. Low current consumption of 32u A typical makes HM5309 ideal for battery-powered applications. The HM5309 is designed specifically to provide a simple application circuit and minimize the size and number of external ponents, making them ideal for consumer electronics applications. The HM5309 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 ponent size. Chip enable input can make HM5309 into ultra-low-current shutdown mode. The HM5309 is available in a space-saving 6-pin SOT23 package.
