DescriptionThe LTC1436IGN-PLL is one member of the LTC1436 family which designed as the high efficiency low noise synchronous step-down switching regulators that drive external N-channel power MOSFETs in a phase lockable, fixed frequency architecture. And it can be used in (1)notebook and palmtop computers, pdas; (2)cellular telephones and wireless modems; (3)portable instruments; (4)battery-operated devices; (5)dc power distribution systems. The operating current level is user-programmable via an external current sense resistor. Wide input supply range allows operation from 3.5V to 30V (36V maximum).
Features of the LTC1436IGN-PLL are:(1)maintains constant frequency at low output currents; (2)dual n-channel mosfet synchronous drive; (3)programmable fixed frequency (pll lockable); (4)wide vin range: 3.5v to 36v operation; (5)low minimum on-time (</=300 ns) for high frequency, low duty cycle applications; (6)very low dropout operation: 99% duty cycle; (7)low dropout, 0.5a linear regulator for cpu i/o or low noise audio supplies; (8)built-in power-on reset timer; (9)programmable soft start; (10)low-battery detector; (11)remote output voltage sense; (12)foldback current limiting (optional); (13)pin selectable output voltage; (14)logic controlled micropower shutdown: iq < 25ma; (15)output voltages from 1.19v to 9v; (16)available in 24-lead narrow ssop and 28-lead ssop packages.
The absolute maximum ratings of the LTC1436IGN-PLL can be summarized as:(1)input supply voltage:36V to -0.3V;(2)topside driver supply voltage (boost): 42V to -0.3V;(3)switch voltage (SW):VIN+5V to 5V;(4)lead temperature (soldering, 10 sec):300°C;(5)storage temperature range:-65°C to 150°C;(6)junction temperature:125°C;(7)operating temperature range:0°C to 85°C;(8)peak driver output current < 10ms (TGS):250mA;(9)peak driver output current < 10ms (TGL, BG):2A.
