LM2576TV-ADJ

The LM2576TV-ADJ is one member of the LM2576 family which is designed as the 3.0 A, 15 V, step-down switching regulator that can be used in (1)simple high-efficiency step-down (buck) regulator; (2)efficient pre-regulator for linear regulators; (3)on-card switching regulators; (4)positive to negative converter (buck-boost); (5)negative step-up converters; (6)power supply for battery chargers. This device is available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version, and the output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.

Features of the LM2576TV-ADJ are:(1)3.3 V, 5.0 V, 12 V, 15 V, and adjustable output versions; (2)adjustable version output voltage range, 1.23 to 37 V +/-4 % maximum over line and load conditions; (3)guaranteed 3.0 A output current; (4)wide input voltage range; (5)requires only 4 external components; (6)52 kHz fixed frequency internal oscillator; (7)TTL shutdown capability, low power standby mode; (8)high efficiency; (9)uses readily available standard inductors; (10)thermal shutdown and current limit protection; (11)moisture sensitivity level (MSL) equals 1; (12)pb-free packages are available.

The absolute maximum ratings of the LM2576TV-ADJ can be summarized as:(1)Maximum Supply Voltage: 45 V;(2)ON/OFF Pin Input Voltage: -0.3V </= V </= +Vin V;(3)Output Voltage to Ground (Steady-State): -1.0 V;(4)Storage Temperature Range: -65 to +150 °C;(5)Minimum ESD Rating (Human Body Model: C = 100 pF, R = 1.5 k): 2.0 kV;(6)Lead Temperature (Soldering, 10 seconds): 260 °C;(7)Maximum Junction Temperature: 150 °C.
