2.5A Step-Down Switching Regulator

LM25005 www.ti.com SNVS411C – JANUARY 2006 – REVISED MARCH 2013 LM25005 42V, 2.5A Step-Down Switching Regulator Check for Samples: LM25005 FEATURES 1 •2 Integrated 42V, 160mΩ N-Channel MOSFET • Ultra-Wide Input Voltage Range from 7V to 42V • Internal Bias Regulator • Adjustable Output Voltage from 1.225V • 1.5% Feedback Reference Accuracy • Current Mode Control with Emulated Inductor Current Ramp • Single Resistor Oscillator Frequency Setting • Oscillator Synchronization Input • Programmable Soft-Start • Shutdown / Standby Input • Wide Bandwidth Error Amplifier • Thermal Shutdown DESCRIPTION The LM25005 switching regulator features all of the functions necessary to implement an efficient, high voltage buck regulator using a minimum of external components. This easy to use regulator includes a 42V, 160mΩ, N-channel MOSFET, with an output current capability of 2.5 Amps. The regulator control method is based upon current mode control utilizing an emulated current ramp. Current mode control provides inherent line voltage feed-forward, cycle-bycycle current limiting and ease of loop compensation. The use of an emulated control ramp reduces noise sensitivity of the pulse-width modulation circuit, allowing reliable control of very small duty cycles necessary in high input voltage applications. The operating frequency is programmable from 50kHz to 500kHz. An oscillator synchronization pin allows multiple LM25005 regulators to self-synchronize or to be synchronized to an external.
