ILC6301 Advance
100mA DC/DC Converter With KeepAlive™ Output
General Description
Features
The ILC6301 series of DC-DC converters represents an advanced generation of energy resource management IC’s for battery operated and portable systems. This device series showcases the unique ability to power down a primary load while maintaining power regulation to a secondary load that must remain continuously active. Termed “KeepAlive™” (KA), this feature can supply auxiliary power to serial port receivers, command receivers or control sensors (i.e. IR, RF) while holding other system blocks in standby or power-down mode. Main and KA™ outputs are user selected via the SEL pin. Overall device control is accomplished with the use of the On/Off pin. Only one output is active at any time.
• Selectable Main (to 100mA) or KeepAlive™ (to 10mA) voltage outputs
• Input voltage operating range 1.8V to 6.0V • 3.0V or 3.3V fixed output voltages (custom
