IMP38HC42ESA

The IMP38HC42ESA is one member of the IMP38 family which is designed as the fixed frequency, high performance, current-mode PWM controller that are pin compatible with bipolar 384x devices but feature improvements resulting from IMP's BiCMOS processing and circuit design.

Features of the IMP38HC42ESA are:(1)384x series pinout with BiCMOS technology; (2)zero cross-conduction current by design; (3)1MHz operation; (4)65ns maximum current-sense delay; (5)120A maximum start-up current; (6)1.5mA maximum operating current; (7)high output current drive: 1.0A, IMP38HC4x and 0.5A, IMP38C4x; (8)20V maximum supply voltage; (9)2.5V, 1%, trimmed error amplifier reference; (10)trimmed oscillator discharge current; (11)pin-for-pin enhanced replacements for Micrel MIC38C/HC4x and GMT38C4x/HC4x.

The absolute maximum ratings of the IMP38HC42ESA can be summarized as:(1)Vcc supply voltage:20 V;(2)Vcc supply current:30 mA;(3)Iout current:1.0 A;(4)current-sense and feedback inputs:0.3V to 5.5V;(5)operation junction temperature:+150°C;(6)storage temperature:-65°C to +150°C;(7)lead soldering temperature (10 seconds):+300°C.
