FEATURES
GENERAL DESCRIPTION
● Operation Voltage 2.5V~6.0V A power good detector and LDO ON/OFF● Built-In Current Limit control is also built-in(metal option). DC/DC
● Built-In UVLO converter is operated on current mode architecture
● Built-In Thermal ShutDown for excellent line and load transient response.
● Built-In LDO ON/OFF Control（Metal Option） 1MHz operation frequency is allowing the use of small surface mount inductor and capacitor. The internal synchronous switch increases efficiency and eliminates the need for an external schottky diode. The AT1367A/B/C/D is a family of
APPLICATIONS
low-noise synchronous step-down DC/DC● Power Supply for Slim Type devices converters that is ideally suited for systems powered form a 1-cell Li-ion battery or from a 3-cell to 4-cell NiCd, NiMH, or alkaline battery. It can also be used to USB-based power system. Block Diagram VBG VBG Vref VREG UVLO VCC Current Sense 5 AGND + SLOPE + R S SW Q OSC CTL Control LDO R5 DELAY Auto Discharge *CTL and...
