Description
Preliminary RT9262/A High Efficiency, Low Supply Current, Step-up DC/DC Converter General .
The RT9262/A is a compact, high efficient, step-up DC/DC converter with an adaptive current mode PWM control loop, providing a stable and high efficie.
Features
* 1.0V Low Start-up Input Voltage High Supply Capability to Deliver 3.3V 100mA with 1V Input Voltage 17μA Quiescent (Switch-off) Supply Current 90% Efficiency 550kHz Fixed Switching Rate Providing Flexibility for Using Internal and External Power Switches Built-in 300mA LDO, also for the Zero-OutputCu
Applications
* providing up to 400mA output current. The 550kHz high switching rate minimized the size of external components. Besides, the 17μA low quiescent current together with high efficiency maintains long battery lifetime. The 1.8V to 5V output voltage is set with 2 external resistors. Both internal 2A swit
