Product Summary
The AT1380P is a single-channel PWM control IC for DC/DC conversion with soft start function and short circuit detection. Adjustable soft start of the AT1380P is programmed with an external capacitor on the SCP pin. The AT1380P is ideal for up, down and fly-back conversion.
Parametrics
AT1380P absolute maximum ratings: (1)Power supply voltage VCC:13 V max; (2)Output source current IO+: -50 mA max; (3)Output sink current IO-: 50 mA max; (4)Allowable dissipation PD SOP-8, Ta ≦+25℃: 570 mW max; (5)PD TSSOP-8, Ta ≦+25℃: 430 mW max; (6)Operating temperature TOP: 0 min +85 ℃ max; (7)Storage temperature Tstg: -55 min +125 ℃ max; (8)ESD Classification MIL-STD-883: Class 2.
Features
AT1380P features: (1)1.8 to13 V supply voltage operating range; (2)Low current consumption: 5 mA in operation, 1μA or less in stand-by; (3)20 kHz to 1 MHz operation frequency range; (4)Provides a fixed output current with minimal supply voltage fluctuations by using an external resistor to set the output current; (5)Totem-pole output.; (6)Built-in soft start circuit.; (7)Built-in timer-latch type short circuit detection and protection (SCP) circuit.
