General Description
The MIC38C4xA are fixed frequency, high performance, current-mode PWM controllers. Micrel’s BiCMOS devices
are pin compatible with 384x bipolar devices but feature several improvements.
Features
? Fast 40ns output rise and 30ns output fall times
? –40°C to +85°C temperature range meets UC284x specifications
? High-performance, low-power BiCMOS Process
? Ultralow start-up current (100μA typical)
? Low operating current (4mA typical)
? CMOS outputs with rail-to-rail swing
? ≥500kHz current-mode operation
?Trimmed 5V bandgap reference
? Pin-for-pin compatible with UC3842/3843/3844/3845
? Trimmed oscillator discharge current
? UVLO with hysteresis
? Low cross-conduction currents
Applications
? Current-mode, off-line, switched-mode power supplies
? Current-mode, dc-to-dc converters.
? Step-down “buck” regulators
? Step-up “boost” regulators
? Flyback, isolated regulators
? Forward converters
? Synchronous FET converters

Micrel Semiconductor
Micrel(中文名一般稱為麥瑞半導(dǎo)體或麥克雷爾,目前已被Microchip公司收購)在半導(dǎo)體領(lǐng)域取得了顯著成就,尤其是在低噪聲穩(wěn)壓IC、低壓差穩(wěn)壓IC以及光通信產(chǎn)品等方面。成立于1978年的Micrel,是全球領(lǐng)先的模擬、以太網(wǎng)和高帶寬市場IC解決方案制造商。自1981年起,Micrel正式具備半導(dǎo)體制造能力,從最初的代工模式發(fā)展成為自主研發(fā)和生產(chǎn)高質(zhì)量模擬電源IC的公司。憑借超過二十年的生產(chǎn)經(jīng)驗,Micrel涵蓋了CMOS、DMOS、Bipolar、NMOS和PMOS等多種制程技術(shù),尤其在電源IC市場上占有重要地位。 Micrel于1994年12月在NASDAQ上市,并于1997年通過IS
