High Efficiency Low-Side N-Channel Controller for Switching Regulators

Check for Samples: LM3488, LM3488-Q1

FEATURES

DESCRIPTION

The LM3488 is a versatile Low-Side N-FET high

•

LM3488Q is AEC-Q100 qualified and

performance controller for switching regulators. It is

suitable for use in topologies requiring low side FET,

such as boost, flyback, or SEPIC. Moreover, the

LM3488 can be operated at extremely high switching

frequency in order to reduce the overall solution size.

The switching frequency of LM3488 can be adjusted

to any value between 100kHz and 1MHz by using a

single external resistor or by synchronizing it to an

external clock. Current mode control provides

superior bandwidth and transient response, besides

cycle-by-cycle current limiting. Output current can be

programmed with a single external resistor.

manufactured on an Automotive Grade Flow

•

8-lead VSSOP package

Internal push-pull driver with 1A peak current

capability

•

Current limit and thermal shutdown

Frequency compensation optimized with a

capacitor and a resistor

•

Internal softstart

Current Mode Operation

Undervoltage Lockout with hysteresis

The LM3488 has built in features such as thermal

shutdown, short-circuit protection and over voltage

protection. Power saving shutdown mode reduces the

total supply current to 5µA and allows power supply

sequencing. Internal soft-start limits the inrush current

at start-up.

APPLICATIONS

•

Distributed Power Systems

Notebook, PDA, Digital Camera, and other

Portable Applications

•

Offline Power Supplies

Set-Top Boxes

KEY SPECIFICATIONS

•

Wide supply voltage range of 2.97V to 40V

100kHz to 1MHz Adjustable and

Synchronizable clock frequency

•

±1.5% (over temperature) internal reference

5µA shutdown current (over temperature)
