IR3846規(guī)格書詳情
DESCRIPTION
The IR3846 SupIRBuck? is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard PWM controller and MOSFETs make IR3846 a space-efficient solution, providing accurate power delivery for low output voltage and high current applications.
IR3846 is a versatile regulator which offers programmability of switching frequency and current limit while operating in wide input and output voltage range.
The switching frequency is programmable from 300 kHz to 1.5MHz for an optimum solution. It also features important protection functions, such as Over Voltage Protection (OVP), Pre-Bias startup, hiccup current limit and thermal shutdown to give required system level security in the event of fault conditions.
FEATURES
? Single 5V to 21V application
? Wide Input Voltage Range from 1.5V to 21V with external Vcc
? Output Voltage Range: 0.6V to 0.86*PVin
? 0.5 accurate Reference Voltage
? Enhanced line/load regulation with Feed-Forward
? Programmable Switching Frequency up to 1.5MHz
? Internal Digital Soft-Start
? Enable input with Voltage Monitoring Capability
? Remote Sense Amplifier with True Differential Voltage Sensing
? Thermally compensated current limit and Hiccup Mode Over Current Protection
? Smart LDO to enhance efficiency
? Vp for tracking applications and sequencing
? Vref is available externally to enable margining
? External synchronization with Smooth Clocking
? Dedicated output voltage sensing for power good indication and overvoltage protection which remains active even when Enable is low.
? Enhanced Pre-Bias Start up
? Body Braking to improve transient
? Integrated MOSFET drivers and Bootstrap diode
? Thermal Shut Down
? Post Package trimmed rising edge dead-time
? Programmable Power Good Output with tracking
? Small Size 5mm x 7mm PQFN
? Operating Junction Temp: -40oC ? Lead-free, Halogen-free and RoHS Compliant
APPLICATIONS
