Introduction
The LM46002 regulator is an easy-to-use synchronous step-down DC/DC converter capable of driving load currents up to 2A with an input voltage range of 3.5V to 60V. The LM46002 delivers excellent efficiency, output accuracy, and dropout voltage in a very compact solution size. Peak current mode control is employed for simplified control loop compensation and cycle-by-cycle current limiting. Optional features include programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, adjustable soft-start and tracking, providing a flexible and easy-to-use platform for a wide range of applications. Discontinuous conduction mode and automatic frequency reduction at light loads improve light-load efficiency. The device family requires minimal external components. The pin arrangement simplifies and optimizes PCB layout and routing. Protection features include thermal shutdown, VCC undervoltage lockout, cycle-by-cycle current limiting, and output short-circuit protection.
Features
- Regulator quiescent current 27μA
- High efficiency under light load (DCM and PFM)
- Compliant with EN55022/CISPR 22 EMI standards
- Integrated synchronous rectification
- Adjustable frequency range: 200kHz to 2.2MHz (default 500kHz)
- Synchronization to external clock frequency
- Internal compensation
- Stable with most capacitor combinations including ceramic, polymer, tantalum, and aluminum capacitors
- Power good flag
- Soft-start into pre-biased loads
- Internal soft-start: 4.1ms
- Soft-start extendable via external capacitor
- Output voltage tracking
- System UVLO programmable via precision enable
- Output short-circuit protection with hiccup mode
- Thermal shutdown protection
- Create custom designs using LM46002 with WEBENCH Power Designer
Applications
- Industrial power supplies
- Telecom systems
- Automotive applications below AM band
- Commercial vehicle power supplies
- General-purpose wide input voltage regulation
- High-efficiency point-of-load regulation
