Part number lm3488mmx

BRAND National Semiconductor [NS]

Packaging 8-tssop

Date code 10+

Price 3~3.5usd

Summary 8-MSOP, high performance controller, Internal softstart, 45V, 1.0A

Description as follow:

The LM3488MMX is a versatile Low-Side N-FET high performance controller for switching regulators. It is suitable for use in topologies requiring low side FET, such as boost, flyback, SEPIC, etc. Moreover, the LM3488MMX can be operated at extremely high switching frequency in order to reduce the overall solution size. The switching frequency of LM3488MMX 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. The LM3488MMX 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. The applications of LM3488MMX are: (1)Distributed Power Systems; (2)Notebook, PDA, Digital Camera, and other Portable Applications; (3)Offline Power Supplies; (4)Set-Top Boxes.

Parametrics

LM3488MMX absolute maixmum ratings: (1)Input Voltage: 45V; (2)FB Pin Voltage: -0.4V < VFB < 7V; (3)FA/SYNC/SD Pin Voltage: -0.4V < VFA/SYNC/SD < 7V; (4)Peak Driver Output Current (<10μs): 1.0A; (5)Power Dissipation Internally Limited; (6)Storage Temperature Range: -65℃ to +150℃; (7)Junction Temperature: +150℃; (8)ESD Susceptibilty, Human Body Model (Note 2): 2kV.

Features

LM3488MMX features: (1)8-lead Mini-SO8 (MSOP-8) package; (2)Internal push-pull driver with 1A peak current capability; (3)Current limit and thermal shutdown; (4)Frequency compensatiooptimized with a capacitor and a resistor; (5)Internal softstart; (6)Current Mode Operation; (7)Undervoltage Lockout with hysteresis.
