The ADP3026 is a high-efficiency notebook computer power supply controller with a wide input voltage range (6.5 V to 25 V) and up to 96% conversion efficiency.
The ADP3026 is a highly efficient dual synchronous buck switching regulator controller designed to convert battery or adapter input into system supply voltages required in notebook computers. It utilizes a dual-mode PWM/Power Saving Mode architecture to maintain efficiency across a wide load range and features an integrated current sense circuit that eliminates the need for external resistors.
The device provides two fixed output voltages of 3.3 V and 5 V with a switching frequency of 300 kHz. It includes extensive protection functions such as programmable soft-start, undervoltage lockout (UVLO), and integrated output undervoltage/overvoltage protection. The controller is available in a 28-lead TSSOP package.
