  The CXSD62309B is a 1.5MHz constant frequency,current mode step-down converter. h0Q嘉泰姆

It is ideal for portable equipment requiring very high current up to 2A from single-cell h0Q嘉泰姆

Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. h0Q嘉泰姆

The CXSD62309B also can run at 100% duty cycle for low dropout operation, extendingh0Q嘉泰姆

battery life in portable systems while light load operation provides very low output rippleh0Q嘉泰姆

 for noise sensitive applications. The CXSD62309B can supply up to 2A output load current h0Q嘉泰姆

from a 2.3V to 6V input voltage and the output voltage can be regulated as low as 0.6V. h0Q嘉泰姆

The high switching frequency minimizes the size of external components while keeping h0Q嘉泰姆

switching losses low. The internal slope compensation setting allows the device to operateh0Q嘉泰姆

 with smaller inductor values to optimize size and provide efficient operation. The h0Q嘉泰姆

CXSD62309B is offered in a low profile 6-pin, SOT package, and is available in an adjustableh0Q嘉泰姆

 version. This device offers two operation modes, PWM control and PFM Mode switching h0Q嘉泰姆

control, which allows a high efficiency over the wider range of the load.h0Q嘉泰姆
