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.
