Chipower CE8303
The CE8303 is a CMOS PFM-control step-up Low voltage operation: switching DC/DC converter. The PFM controller allows the duty ratio to be automatically switched according to the load, enabling Startup at 0.9 V @IOUT = 1 mA Working frequency: 300KHz External parts: Coil, capacitor, diode products with a low ripple over a wide range, Accuracy of ±2% high efficiency, and high output current. With High efficiency： 87%（typ.） the CE8303, a step-up switching DC/DC converter can be configured by using an external coil, capacitor, and diode.| Part No. | CE8303 |

FEATURES
The CE8303 is a CMOS PFM-control step-up● Low voltage operation: switching DC/DC converter. The PFM controller allows the duty ratio to be automatically
● switched according to the load, enabling
● Startup at 0.9 V @IOUT = 1 mA Working frequency: 300KHz External parts: Coil, capacitor, diode products with a low ripple over a wide range,
● Accuracy of ±2% high efficiency, and high output current. With
● High efficiency： 87%（typ.） the CE8303, a step-up switching DC/DC
● converter can be configured by using an
● external coil, capacitor, and diode. The built-in Shutdown function Low ripple, Low noise MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit to prevent it from being damaged. This feature, along with the mini package and low current consumption, makes the CE8303 ideal for applications such as the power supply unit
