Enhanced Product (EP) Single
Synchronous Buck Pulse-Width
Modulation (PWM) Controller
FN6613.1
Features
• Specifications per DLA VID V62/08610
The ISL6406MREP and ISL6406MVEP are adjustable
frequency, synchronous buck switching regulators optimized
for generating lower voltages for distributed DC/DC
architectures. Both devices feature an adjustable output
voltage.
Designed to drive N-Channel MOSFETs in a synchronous
buck topology, the ISL6406MREP and ISL6406MVEP
integrate the control, output adjustment and protection
functions into a single package.
• Full Mil-Temp Electrical Performance from -55°C to +125°C
• Controlled Baseline with One Wafer Fabrication Site and
One Assembly/Test Site
• Full Homogeneous Lot Processing in Wafer Fab
• No Combination of Wafer Fabrication Lots in Assembly
• Full Traceability Through Assembly and Test by
Date/Trace Code Assignment
• Enhanced Process Change Notification
The ISL6406MREP and ISL6406MVEP provide simple,
single feedback loop, voltage-mode control with fast
transient response. The output voltage can be precisely
regulated to as low as 0.8V. The error amplifier features a
15MHz gain-bandwidth product and 6V/μs slew rate which
enables high converter bandwidth for fast transient
performance.
• Enhanced Obsolescence Management
Protection from overcurrent conditions is provided by
monitoring the rDS(ON) of the upper MOSFET to inhibit PWM
operation appropriately. This approach simplifies the
implementation and improves efficiency by eliminating the
need for a current sense resistor.
• Simple Single-Loop Control Design
- Voltage-Mode PWM Control
The wide programmable switching frequency range of
100kHz to 700kHz allows the use of small surface mount
inductors and capacitors. The device also provides external
frequency synchronization making it an ideal choice for
DC/DC converter applications.
• Eliminates Need for Up-Screening a COTS Component
• Operates from 3.3V/5V Input
• 0.8V to VIN Output Range
- 0.8V Internal Reference
- ±2.1% Reference Accuracy Over-Temperature
• Fast Transient Response
- High-Bandwidth Error Amplifier
• Lossless, Programmable Overcurrent Protection
- Uses Upper MOSFET’s rDS(on)
• Programmable Switching Frequency 100kHz to 700kHz
• External Frequency Synchronization
• Internal Soft-Start
