General Description

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 stand by 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.

Features

• 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 requirements contact Impala)

• Internal controlled synchronous operation requires no external diode

• Optimized design requires a minimum of external components One inductor and three capacitors

• Low power OFF mode, < 1µA @ VDD = 1.8V

• Internal oscillator frequency ~ 210kHz ±15%

• Condition Flag output
