UC2825AMDWREP

Texas Instruments · DC-DC Converters · SOIC-16-300mil

UC2825AMDWREP from Texas Instruments, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 INV input Inverting input to the error amplifier.
2 NI input Noninverting input to the error amplifier.
3 EAOUT output Output of the error amplifier, used for loop compensation.
4 CLK/LEB output Buffered output of the internal oscillator that also sets the leading-edge blanking period through an external capacitor, with clock output current rated to -5 mA.
5 RT input Timing resistor connection for oscillator frequency programming, with recommended values from 1 kΩ to 100 kΩ.
6 CT input Timing capacitor connection for oscillator frequency programming, which should be connected to device ground with minimal trace length.
7 RAMP input Noninverting input to the PWM comparator with 1.25-V internal offset, serving as feed-forward input in voltage-mode operation or slope-compensation input in peak current mode.
8 SS input Soft-start pin that also acts as the maximum duty cycle clamp, with soft-start sink current rated to 20 mA.
9 ILIM input Input to the current-limit comparator, which terminates the pulse above the 1-V threshold after blanking and sets the fault latch above 1.2 V.
10 GND power_in Analog ground return for the control circuitry.
11 OUTA output High-current totem-pole output A of the on-chip drive stage, rated 0.5 A DC and 2.2 A pulse (0.5 ms) source or sink.
12 PGND power_in Ground return for the output driver stage, which should be kept separate from analog ground and is rated ±0.2 V.
13 VC power_in Power supply for the output stage, rated to 22 V absolute maximum and to be bypassed with a low-ESL ceramic capacitor placed with minimal trace length.
14 OUTB output High-current totem-pole output B of the on-chip drive stage, rated 0.5 A DC and 2.2 A pulse (0.5 ms) source or sink.
15 VCC power_in Power supply for the device, rated to 22 V absolute maximum and to be bypassed with a low-ESL ceramic capacitor placed with minimal trace length.
16 VREF power_out 5.1-V reference output, which should be bypassed with a low-ESL ceramic capacitor placed with minimal trace length to the ground plane.
