UC3844D8 Ratings and Reviews

S***y

The product was almost 4 (four) months...

S***a

Fast shipping, order delivered in 19 days in India. Latches with each other well. Double sided tape at bottom. Connector in power rails are loose (are not very springy), doesn’t hold the wire well. However, it’s functional. For the price it’s worth every penny. Real value for money.

UC3844D8 Description

***Components: In a Pack of 5, Texas Instruments UC3844D8, PWM Current Mode Controller, 1 A, 500 kHz 8-Pin SOIC

***p One Stop Japan: Current Mode PWM Controller 1A 8-Pin SOIC Tube

***ical: UCx84x Current-Mode PWM Controllers

***ark: Pwm Controller, Current Mode, Soic-8; Input Voltage:25V; Output Voltage:13.5V; Output Current:200Ma; Supply Voltage Min:10V; Supply Voltage Max:30V; Controller Ic Case Style:soic; No. Of Pins:8Pins; Frequency:450Khz; Operating Rohs Compliant: Yes

***AS USD: The UCx84x series of control integrated circuits provide the features that are necessary to implement off-line or DC-to-DC fixed-frequency current-mode control schemes, with a minimum number of external components. The internally implemented circuits include an undervoltage lockout (UVLO), featuring a start-up current of less than 1 mA, and a precision reference trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure latched operation, a pulse-width modulation (PWM) comparator that also provides current-limit control, and a totem-pole output stage that is designed to source or sink high-peak current. The output stage, suitable for driving N-channel MOSFETs, is low when it is in the off state.

***AS INSTRU: The UCx84x family offers a variety of package options, temperature range options, choice of maximum duty cycle, and choice of turnon and turnoff thresholds and hysteresis ranges. Devices with higher turnon or turnoff hysteresis are ideal choices for off-line power supplies, while the devices with a narrower hysteresis range are suited for DC-DC applications. The UC184x devices are specified for operation from –55°C to 125°C, the UC284x series is specified for operation from –40°C to 85°C, and the UC384x series is specified for operation from 0°C to 70°C.
